No comment on the JB weld but use the special fuel injection hose and the proper fuel injection clamps. Hg for ½-inch diameter hose.
They work and although about double the cost of good regular fuel line and clamps it will outlast them more than 31 on an EFI system.
Fuel injection hose vs regular fuel line. Fuel injection receives higher air pressure vs. A regular fuel line. The hose initially receives the first burst of fuel from the fuel pump.
A regular fuel line transports processed fuel used as energy from one part of the vehicle to another. These hoses are generally referred to as Fuel Injection Hose because they are rated for a much higher pressure - but more importantly they are rated for use with ALL fuel types including alcohols fuel-oils diesels etc etc. Modern fuel line hoses are necessary for modern fuels.
The fuel line. Comes from the tank to the fuel filter goes tru the fuel filter to the fuel line going to the engine injector fuel lines which deliver a mist of fuel to the engine cylinders to. Standard neoprene fuel hose can be used for fuel PCV and EEC systems on all vehicles where working pressures are under 50 psi or vacuum ratings are under 24-in.
Hg for 716-inch and smaller inside-diameter sizes 10-in. Hg for ½-inch diameter hose. Fuel line is a petroleum-resistant nitrile tube with a covering that resists weathering ozone and heat and can be used for ethanol-laced fuels and.
GoodYear rates there hoses with R rating is what I have learned. The most common fuel line is R6 - Gasoline but R10 is the only hose that GoodYear makes that is rated for Diesel. I bought 25ft of R10 from my local AutoZone and it cost me like 58.
I spent three hours trying to find the proper fuel hose for my FASS. Once fuel lines are degraded rubber hose particles can contaminate and obstruct fuel injectors and carburetor passages hindering performance and causing multiple problems. Earls Performance fuel hoses that address these issues with multi-layer technology designed to withstand the corrosive properties of modern fuel.
Excessive pressure drop in the fuel lines feeding a carburetor or EFI system will inhibit their proper function and in the case of a bypass or return style regulator excessive pressure drop through a return line will squelch the regulators ability to operate correctly. To deliver fuel at the correct flow rate and pressure careful consideration of fuel line diameter and length as well as whether the application. I would only use regular non fuel injection automotive hose from your local auto parts store.
Im not an expert on the clear lines but unless you go with an expensive high end type my thought is you will run the risk of cracking wear on friction points and kinking. Regular fuel line is resistant to these things and much cheaper. Clear fuel lines vs.
Do not go by the outside diameter of the the fuel line when buying a replacement. Its the inside diameter 14 that is important. It is not difficult work to do but it can be time consuming because you dont want to screw up and put a line in the incorrect spot.
Modern fuel line h. Do not replace long runs of hard line with flexible fuel hose. Even the best fuel injection low-permeation fuel line will have some amount of fuel vapor loss.
Also road debris can damage these lines. Making this mistake is very dangerous and it also can be difficult to seal the connection between the metal line and the hose that could be under 50 psi or more of pressure. Auto stores sell two grades the regular stuff and the high pressure stuff for fuel injection cars.
The regular stuff is fine for outboards. Unless it is fuel injected I supose. Disregarding the slight size differencesmost booster hoses are either 1132 or 1532 in.
ID while PCV hoses usually run 38 716 or 12 inPCV hoses are generally rated to withstand 10 to 24 inHg of vacuum while brake booster hoses are rated for 30 inHg. Barricade fuel injection hose is a low permeation multi-fuel compatible hose that virtually eliminates fuel vapor loss thanks to our 5-layer GreenShield barrier technology. Works with multiple fuels approved for use with leaded and unleaded petrol diesel biodiesel up to B-100 E-10 E-15 E-85 100 methanol ethanol and gasohol fuels.
I think the difference between fuel and trans rubber line is the trans line withstands the oil and additives in the trans fluid much longer than the hose designed for gasoline. I tried once to hard plumb an add on cooler and couldnt get it to not leak I thought it was because of. Fuel injection hose is perfect.
Hydraulic hose will work fine to. The only down fall is its big thick and harder to move around then fuel line. It will deteriorate from the inside out and really make a mess of your fuel system.
Then it will spring a leak. The SAE 30R6 and 30R7 neoprene fuel line is for standard gasoline gasoline with ethanol gasoline lead-free fuel and diesel fuel resistant. The fuel injection hose SAE 30R9 can be used with 100 methanol.
Just make sure you ask for fuel injected fuel line. Its reinforced and made for your application high pressure line. Buy enough to overlap the hard line by about 2 inches on each side and use hose clamps like the ones in the pic the standard small worm gear screw style ones arent the hottest for high pressure they dont tighten down evenly when they are that small.
Type 825 hose is an excellent choice for fuel feed hoses in most street applications. It also makes a great pick-up hose inside the fuel cell. It will withstand exposure to any type of fuel it resists fuel vapor penetration and its operating pressure rating far exceeds the pressures in most EFI systems.
This kit is used to repair factory fuel lines. Like the 4th gen camarofirebird fuel lines. They are like nylon.
You could use hard line and put this hose on that to your fuel rail and pump or just run that line. If you know someone with a napa account you can get a break on the prices. We use this stuff at the GM shop to repair lines.
Adapter Fittings Adapter Fittings also known as Standard Fittings or Union Fittings are commonly used to connect fuel line tubes and hoses to fuel pumps fuel regulators and fuel filters. While Adapter Fittings are available in SAE size configurations most high-end racing and performance fuel systems use those manufactured to AN. No comment on the JB weld but use the special fuel injection hose and the proper fuel injection clamps.
They work and although about double the cost of good regular fuel line and clamps it will outlast them more than 31 on an EFI system.
