A boat also needs less fuel line and pump than a drag/ street car because the tanks in a boat are even with or in front of the engine and much closer, so the fuel doesn't need to be pulled foward against the "G" load of the launch for 12 feet. For filling and maintaining your boat’s fuel tank systems, turn to the professionals at Wholesale Marine. It includes our high quality primer bulb, premium A1 hoses and the engine and tank connectors. Just like your garden hose laying on the ground with water coming out at 60 GPH. bigdee Commander. Yes, the 2 mic will load quicker (get dirty) and the restriction would rise faster, but isn’t that what it should do? We’ve been serving local Ventura County, California since 1980 as a custom boat builder, repower specialist, designer, and supplier of equipment to builders, commercial fishermen, and recreational users. Units of measurement can vary, but inches of Mercury (Hg) seems to be most accepted. Also Mates to Larand Tank Outlet: L-7410 Most all fuel return line systems are “open”, meaning that the fuel returns to a fuel tank, and there are no valves or other restrictive components within the system to cause any, or much added restriction.

I think it was time A perfect example of this is when a typical owner thinks that a 2mic filter is more restrictive than a 10 mic filter of the same size (like a Racor 1000 element at 2 mic or 10 mic, both new, at a flow rate of 1 GPM. So, where could the restriction come from, you ask? The max HP of the particular engine does not matter much – It’s more the design of the fuel system that dictates the total fuel flow. So a -10 would be 10 mm, -20 twenty mm, and so on? IMHO! But there is a little more to it than that. Regardless of the units of measure used, fuel restriction values need to be very low, and in a general sense, the lower the better when the system is fresh or new as this gives the operator more time between filter maintenance. Anyone know what size carburetor fuel line hose my 1985 Bayliner Capri 85hp Force Motor takes? 11-1/2, Vulkan Vulkardan-E Coupling (2K3411S020) SAE No. Although kind ugly and a touch complex, it was low on restriction because of ample sizing (mostly 3/4″ pipe size) of all the fittings & hose sizes Top rpm is about 47-4800, and it just feels like the motor has more in it, but just can't rev up any more. In actuality, both elements would be under .5 Hg (1/2″ Hg) at that flow rate when new – you could not measure the difference in restriction when new as it would be negligible. Joined Jul 27, 2006 Messages 2,634. Some may come from an inline return fuel cooler (not much if they are sized right) and friction inside the fuel line with fuel flowing thru it, which brings us to what this discussion is about – Fuel Line Restriction, and how it interacts or affects overall fuel restriction on both the supply and the return fuel system on a diesel engine. My question is pretty much, Is a 3/8 rubber line from the tank to the pump,-9 feet, limiting my fuel supply at high rpm?

The picture shows what a full fuel line assembly looks like. It’s so typical that marine certifications are way behind new thinking and design – “Fluff”, politics, and old fashioned ideas seem to take the center stage so much in this industry that many times we just march by our own drum when we see something that offers a better way to accomplish the task Items 1-12 of 54. Summer is comming here, so I will be getting the boat out soon to start working on it. It also typically produces a louder engine that … 4.3L/262ci Low Pressure Fuel Pump to Carburetor Fuel Line. Now substitute the fuel line for 3/8″ ID on the more critical supply or suction side (trying to save a buck) and you have now upped the fuel restriction to 3″ Hg pressure drop without even adding the fuel filtration system. The fuel line after the pump can be the next smaller size. Is it worth the extra cost of buying marine fuel line over just fuel line for cars? High-quality fuel assembly components must be securely attached to prevent potentially dangerous fuel line leaks. $33.01 - $53.69. All fuel line assemblies use a compounded, tough and pliable UV-resistant hose that promotes maximum fuel flow. The U.S. Coast Guard addresses fuel line requirements in the code of federal regulations (CFR) that applies to recreational boats: CFR Title 33. The Best Universal Fuel Line Assembly Kit with Tank Fitting (Johnson/Evinrude, Mercury, Yamaha) … Most all fuel return line systems are “open”, meaning that the fuel returns to a fuel tank, and there are no valves or other restrictive components within the system to cause any, or much added restriction.

Boat Accessories Australia has a great range of fuel line connectors for any application from brands like Mercury, Honda, Suzuki, Yamaha, Nissan-Tohatsu, OMC and more. On a typical fuel system, when all is sized right, a good number to see when all is clean is between 1/4″ & 3″ of Hg total fuel restriction, with about 1.0 to 2″ Hg most common in a well designed fuel system. For Marine Power 3.0L engines fuel filter to pump. Just wondering and the boat I bought just has the vehicle fuel line in it. I am in Vegas and would be willing to work for food. Some may come from an inline return fuel cooler (not much if they are sized right) and friction inside the fuel line with fuel flowing thru it, which brings us to what this discussion is about – Fuel Line Restriction, and how it interacts or affects overall fuel restriction on both the supply and the return fuel system on a diesel engine. The fuel line hoses are the standard 18 inches to the tank and 54 inches to the engine. View All; Fishing Boat Seats ... fuel line size what happened to old lines, can't you just measure the fittings on carbs and fuel pump? Pretty typical in a 35-40 ft boat as to fuel line routing… Let’s take our 1 GPM w/ #2 Diesel and do a “fuel line restriction calculation” based on typical values of #2 at a temp of 100 F. I’ll use a specific gravity of .85 and a viscosity of 3.0 centipoises (these would be reasonable numbers). Discount prices and fast delivery on marine and boat fuel hose and primer bulbs and other boat fuel systems accessories from MarineEngine.com. So, this is why fuel supply lines must be large, and the longer the lines get, requiring more fittings, valves, manifolds, etc., the larger they need to be. Eastern Marine sells OE compatible outboard motor fuel line and tank fittings for Mercury, Mariner, Johnson, Evinrude, Yamaha, and Honda boat motors. Car engines have smaller valves, less compression, and even the most popular "RV" cam used by the car guys is much smaller than the stock jet boat grind. Check the cam and dist. Yes, the 2 mic will load quicker (get dirty) and the restriction would rise faster, but isn’t that what it should do? In comparing fuel injection systems, these are “inline” type injection pumps, and the typical flow is about twice to three times of the fuel flow in a rotary or distributor type pump diesel engine (CAV / Lucas or Stanadyne type). We carry an extensive line of boat gas tanks from leading manufacturers for both inboard and outboard engine fuel tank systems. We get it. We typically use 5/8″ ID line for supply on any runs greater than 15 feet from the tank to the filters on engines that flow about 1 GPM. Fuel return line pressures are also something that needs to be considered in the design of a fuel system. Compatible with all fuel tanks with standard 1/4" NPT output.

Not sure on BBC for timing but I would set that with 3000RPM and most idle at 1000-1200 out of the water. I did not know they were "tight", as I never had the motor apart before. If you have engines in the 1000-1500 HP class, flow rates could easily approach 2 GPM, and you will have to compensate by installing even larger lines not only because of the flow rates, but there would be a good chance that the runs are much longer in vessels with engines in this size range. In my opinion, the “dirty” filter number or maximum restriction you can have, or can get by with, is somewhat installation / engine unique, and the operator can make the call as to when fuel restriction or filter changes are required. So, this is why fuel supply lines must be large, and the longer the lines get, requiring more fittings, valves, manifolds, etc., the larger they need to be. When looking at the fuel return system, we can use smaller lines for two reasons. It is my humble opinion (and I like the sound of my own voice, "Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways totally worn out shouting 'Holy Shit what a ride!" Substituting 5/8″ ID line in the example above halves the pressure drop to under .2 Hg. The regulations address in great detail issues related to gasoline fuel systems. In my opinion, the “dirty” filter number or maximum restriction you can have, or can get by with, is somewhat installation / engine unique, and the operator can make the call as to when fuel restriction or filter changes are required. Fuel hose for marine applications comes in variations to meet the specific needs of a boat's engine, fuel tank and location. Anyway, he put them back the way they were, so that could be part of the problem. But, here is what all seem to not realize. Filter By Category. Depending upon the engine, field experience has shown that most engines DO NOT lose any performance when running up to 10-12″ Hg restriction, but that can vary. I have not even checked timeing,--I just put the distributer back in where it was when I re-built the motor, and it ran the same as it did before the motor spun a bearing. Although not part of the fuel supply system after the tanks, this was a fuel fill hose on a 46 Bertram we re-powered. Just about everybody seems to equate fuel restriction with the fuel filtration system and it’s design, and never thinks about the fuel line as being a major factor in this equation, even when all is new and clean. Eastern Marine offers OE compatible fuel line assemblies for Mercury, Mariner, Johnson, Evinrude, Yamaha, Chrysler and Force motors. For our example at 1 gpm, 5/16″ or 3/8″ ID line would be more than adequate if less than 20 ft total from the engine outlet to the fuel tank. Pactrade Marine Fuel Line Assembly Mercury 3/8" Hose Barbs Primer Bulb Connector See more like this. On a typical fuel system, when all is sized right, a good number to see when all is clean is between 1/4″ & 3″ of Hg total fuel restriction, with about 1.0 to 2″ Hg most common in a well designed fuel system. Because of the popularity the 6 cylinder 6BTA or 6CTA Cummins (not that it really matters), we’ll use these engines as a basis for this discussion. If you are in doubt go with a fuel return system it works great , keeps the fuel supply charged all the time. Pretty typical in a 35-40 ft boat as to fuel line routing… This would be about normal.

The new designator, Type A1-15 describes hose that is less permeable than your old hose, which was simply rated A-1. We’ll get to that later as that is a slightly different subject. (External pumps push fuel. Mercury specifies 2.5" Hg. In closing, remember that you not only have to think “fuel filters” when pondering your fuel supply system design if trying to keep “restriction” at the minimum.. Boat fuel lines and hoses in any boat’s fuel systems are essential in ensuring safe boat operation and trouble-free performance. Inside the ½” fuel line the fuel would be traveling at 2 ft/second and inside the 3/8″ fuel line just over 3 ft per second. Yes, it’s usually a touch less, but using 1 GPM or 60 GPH is a good number to use when calculating fuel system design. Tell me more about Fuel Tanks and Accessories. Tell me more about Fuel Lines and Hoses (Other) Shop Products. Units of measurement can vary, but inches of Mercury (Hg) seems to be most accepted. One, the maximum allowed value for the pressure drop is usually 2-4 times more and the return flow is always less (at least to some extent) than the total fuel flow. A boat also needs less fuel line and pump than a drag/ street car because the tanks in a boat are even with or in front of the engine and much closer, so the fuel doesn't need to be pulled foward against the "G" load of the launch for 12 feet. Back Boat Seats. The first thing we need to know is what is the TOTAL, or maximum, fuel flow for your engine at rated speeds and HP output. Also compatible with 7.4L Jet engines, pump to carburetor. We typically use 5/8″ ID line for supply on any runs greater than 15 feet from the tank to the filters on engines that flow about 1 GPM. The Use thread sealant when connecting to tank Attwood Universal Sprayless Connector replaces traditional tank fittings and eliminates spray when connecting or disconnecting fuel fittings. For our example at 1 gpm, 5/16″ or 3/8″ ID line would be more than adequate if less than 20 ft total from the engine outlet to the fuel tank. A little help will go a long ways. Add to cart. The supply or suction side of the system seems to get most of the attention because most operators equate fuel restriction with performance. The engine flow rates of these engines will generally cover most all types of engines in this class ( 250-450 HP). Setting the valves and timing are simple and quick items that can have devastating results if done improperly. The anti-siphon valve accounts for about 1.8" Hg and a spin-on fuel filter adds about 0.5" Hg. Yes, you can equate the two but not as most think. This manifold feeds 2 x QSM 630’s and 2 x 20Kw gensets with #10 hose for the main and #8 hose for the generators My mechanic did ask why my rocker arms were tightend down so much when he rebuilt the motor. Regardless of the units of measure used, fuel restriction values need to be very low, and in a general sense, the lower the better when the system is fresh or new as this gives the operator more time between filter maintenance. It offers superior resistance to U/V, ozone and alcohol enhanced fuel. Boat is a high compression 454, with a 750 holley. Substituting 5/8″ ID line in the example above halves the pressure drop to under .2 Hg. Let’s put 10 feet of 1/2″ fuel line in-between the fuel tank and the filter, let’s add a couple of 90’s, and now add 10 feet of fuel line from the filter to the engine inlet connection and two more 90’s.
