what size is boat fuel line

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. 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. I ran -10 lines and then -8 lines to the bowls. 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. Marine Gas Tanks. Sierra Marine 5/16 Inch x 8 Foot Long Fuel Line Assembly Part #: 18-8013EP1 Line: SIE 11-1/2, Vulkan Vulkardan-E Coupling (2K3411S004) SAE No. TIMINATOR, Quote from: iloveitloud on March 28, 2011, 07:29:28 PM, Quote from: Brad @ SoCalJetBoats.com on December 22, 2009, 07:40:31 PM, Quote from: IRRebel on June 11, 2011, 07:30:45 PM, Quote from: GT Jets on March 28, 2011, 10:24:58 PM, Quote from: Horizonjet on April 05, 2011, 02:24:00 PM, Quote from: GT Jets on April 05, 2011, 05:15:03 PM, Quote from: IRRebel on April 05, 2011, 05:35:26 PM, Boat #1: 1992 Carrera 20.5 Elite (I/O bitches), Boat #2: 19' Bubble deck Jet BBC Berkeley. Marine hose is rated for 40 psi and will work in a … Seaboard Marine delivers “Guaranteed Better Than Factory” Performance, Parts, Design, and Engineering for Cummins and other Marine Diesel applications. Smaller boats that range in size from thirty to forty feet will typically offer options for both gas engines and diesel engines: Diesel tends to be more expensive both in terms of the motor and the fuel itself. Check the cam and dist. 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. The pressure drop at 1320 HP thru a 3/8” steel line might be around 5 psi. Add to cart. 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. Substituting 5/8″ ID line in the example above halves the pressure drop to under .2 Hg. We carry an extensive line of boat gas tanks from leading manufacturers for both inboard and outboard engine fuel tank systems. High-quality fuel assembly components must be securely attached to prevent potentially dangerous fuel line leaks. 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? Go. 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). Call us. Yes the pressure drop thru a ½” line is a nominal 5 feet versus 35 feet for the 3/8” id fuel line. go up to the next bigger fuel line. The regulations address in great detail issues related to gasoline fuel systems. Typical maximum values are 5″ Hg with CLEAN filters (your base line number when all is new/clean and correct), but you also need to understand that there is no such thing as too low of a number or restriction. 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. 16" 3/8 NPT Fuel Line. I'll be getting it out soon, and have more info. 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. Oftentimes the argument is made against fitting a fuel/water separator on a boat if it has removable fuel tanks. 5/16'' 8mm Fuel Line Assembly, 10ft Fuel Hose Line Fit for Yamaha Outboard Marine Boat Motor, Fuel Gas Hose Line Assembly, Rubber 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. When using E85, alcohol, methanol, etc. I now run -12 lines out of the tanks including 3/4" ID custom made pickup tubes then from the pump to the fuel rails -10. 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 supply or suction side of the system seems to get most of the attention because most operators equate fuel restriction with performance. 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. 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). The picture shows what a full fuel line assembly looks like. 4.3L/262ci Fuel Line Low Pressure Fuel Pump to Carburetor. I would get a fuel gauge...that way you know.

They don't pull it very well.) All fittings are built to OEM specifications for replacement parts. 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. Outboard Motor Fuel Fittings. We recommend you install a 100 Micron In-Line Fuel Filter between the tank and the pump. Tell me more about Fuel Lines and Hoses (Other) Shop Products. Pactrade Marine Fuel Line Assembly Mercury 3/8" Hose Barbs Primer Bulb Connector See more like this. 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. 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. I think it was time 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. 99 Marine hose must have the SAE J1527 Style R1 rating emblazoned on the hose to pass as seaworthy. 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. If I remember correctly back in the days when I worked at the Phoenix Sea Ray plant then the red stripe is the marine stuff.

All fuel line assemblies use a compounded, tough and pliable UV-resistant hose that promotes maximum fuel flow. We just ended up w/ a .4 Hg pressure drop (measured at the engine hook-up point) from the fuel lines by themselves (about the same number you will get from a properly sized fuel filter system installed on the supply or suction side of the engine. Has newer Mallory Unilite distributer, and Taylor 8mm wires. So, where could the restriction come from, you ask? 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. Also compatible with 7.4L Jet engines, pump to carburetor. Obviously, the difference between the two fuel lines is one is smaller than the other. 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 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. Next, we need to know the factory’s maximum values, numbers, or pressure drops that the engine can tolerate to work properly for both the supply side (suction) and the return side (restriction-pressure of the return line). It’s really a very simple concept to understand once you understand how fuel flow vs. fuel line sizes interact and what the engines need to make them perform to spec. Compatible with all fuel tanks with standard 1/4" NPT output. It's pretty old, so no markings on it. Anyone know what size carburetor fuel line hose my 1985 Bayliner Capri 85hp Force Motor takes? Do you have a rev limiter, fuel gauge, A impeller..... No rev limiter, no fuel pressure gauge, do have A impeller. 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. Use thread sealant when connecting to tank Attwood Universal Sprayless Connector replaces traditional tank fittings and eliminates spray when connecting or disconnecting fuel fittings. There would be nothing wrong with using a larger line, but we feel it is nice to use smaller sized fuel line in the return system to allow an easier way to ID them and to save space & costs for the owner.

He had used 1/2″ ID fuel line for all but forgot about his “old” pick-up tubes. Jul 11, 2013 #3 Re: fuel line size. 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.. Items 1-12 of 54. Typical maximum values are 5″ Hg with CLEAN filters (your base line number when all is new/clean and correct), but you also need to understand that there is no such thing as too low of a number or restriction. 3/8's, 5/8's? We just ended up w/ a .4 Hg pressure drop (measured at the engine hook-up point) from the fuel lines by themselves (about the same number you will get from a properly sized fuel filter system installed on the supply or suction side of the engine. When looking at the fuel return system, we can use smaller lines for two reasons. 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 If the line is not in an enclosed area, like on an inboard engine, just buy both connectors, a primer, and the right length of regular black fuel line … Although not “Marine Rated”, many styles of very high quality fuel lines are available for other applications.. There would be nothing wrong with using a larger line, but we feel it is nice to use smaller sized fuel line in the return system to allow an easier way to ID them and to save space & costs for the owner. bigdee Commander. Fuel supply restriction or “pressure drop” is always measured as a negative number because it is on the suction side of the fuel lift or supply pump.

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. Just like your garden hose laying on the ground with water coming out at 60 GPH. ---Crewcheif22 AKA Keith. So a -10 would be 10 mm, -20 twenty mm, and so on? 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 Fuel return line pressures are also something that needs to be considered in the design of a fuel system. In this case, and most any 250-450 HP 6 cylinder diesel that uses an ND EP-9 type or Bosch P7100 fuel injection pump (or a system of similar design), just assume the fuel flow is about 1 GPM. 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. Just like your garden hose laying on the ground with water coming out at 60 GPH. Units of measurement can vary, but inches of Mercury (Hg) seems to be most accepted. 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. 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. Fuel gauge is the first thing I will do. Boat is a high compression 454, with a 750 holley. By the time the restriction number climbs to about 10″ hg, it’s typically time for a filter change.

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. Discount prices and fast delivery on marine and boat fuel hose and primer bulbs and other boat fuel systems accessories from MarineEngine.com. 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. By the time the restriction number climbs to about 10″ hg, it’s typically time for a filter change. Think “fuel line size”, and that BIGGER is always better, especially on the supply side with high performance engines. 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. Wherever you are, find an engine guy that is willing to help you with the basics.
