What size is Harley fuel line?
What size is Harley fuel line?
Factory lines are 1/4″.
What size fuel line do I need for fuel injection?
Fuel pumps are sized to feed your system with enough fuel to optimize engine performance….Recommended Size, Based on Horsepower.
| Recommended Fuel Line Size (from the tank to the pump) | ||
|---|---|---|
| Engine Output | Size (inches) | Size (AN) |
| 350 hp or less | 5/16 in. | -5 |
| 350-450 hp | 3/8 in. | -6 |
| 450-650 hp | 1/2 in. | -8 |
What PSI is fuel injection hose?
Regular Fuel Line: PSI. Fuel injection hoses must be able to take air pressure of at least 50PSI. However, an SAE 30R9-rated fuel injection hose would be able to withstand 100 PSI. A PTFE hose with AN6 can take pressure up to 2500 PSI.
Is Fuel Injection hose submersible?
A Hose That’s Fortified, Inside and Out Ordinary fuel line is designed to handle fuel on the inside only. With in-tank applications, gasoline also comes in constant contact with the outside hose surface, making it vital to utilize a hose that’s engineered to be submersible.
How much HP can 6AN?
“A rule of thumb; 5/16″ (-5AN) will support up to 300 horsepower, 3/8″ (-6AN) will cover up to 500 HP, and 1/2″ (-8AN) is good to 700HP.” I would assume this is with lower fuel pressures than what these motors use…so I would bet on a bit more.
Does size of fuel line matter?
Does size really matter when it comes to fuel lines? According to the fuel delivery system experts at Fuelab, it does. It’s because fuel line size and length have a direct effect on the amount of fuel pressure drop your fuel system will experience.
How much pressure is in a fuel return line?
around 40 PSI in an EFI system, though it could be higher or lower depending upon the application. The return line should only have residual pressure on it…a PSI or two caused by the reistance of the fuel line to flow.
What is a fuel injection hose?
To find the right fuel hose, you just have to know what you’re going to use it for, and remember what the laws governing its use are in your area. A fuel hose is a reinforced rubber hose in a vehicle that carries the fuel from a fuel tank to a different part of the vehicle, usually the fuel pump.
What is the best fuel hose to use?
The best solution is a material called PTFE. That stands for polytetrafluoroethylene—a plastic material that is best known as Teflon in one specific variation. This material is impervious to the degenerative effects of fuel that also creates a vapor barrier so fuel vapors cannot leak past.
What type of fuel line is submersible?
Gates Submersible Fuel Line Hose is capable of handling gasoline, alcohol-extended gasoline, ethanols, biodiesel or diesel fuel in fully-immersed, mobile and stationary applications. It contains a special compound, Fluoroelastomer, which resists gas permeation and aging.
How much HP can a 3/8 fuel line support?
A 3/8”id fuel line can easily support 600 HP given sufficient “pump head”!
How much HP does 8AN fuel line support?
An -8 can handle way more than 600 hp.
Can a carbureted fuel line work with EFI?
Back in the early days of aftermarket EFI systems, the great veterans of carbureted fuel delivery systems would scoff at running a small EFI return fuel line saying “It will never work!” They would also look at the much smaller return orifice in the EFI regulator and say “It will not flow enough!”
How is the size of a fuel line important?
To deliver fuel at the correct flow rate and pressure, careful consideration of fuel line diameter and length, as well as whether the application is carbureted or EFI, is very important.
What happens if you drop the fuel line?
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 regulator’s ability to operate correctly.
How is fuel line size sensitive to carbureted system?
Graph B. shows that by adding just two psi of line drop to this example pump, we can lower the available flow rate from 110 gph to 80 gph (over a fourth of the total capacity). This example shows carbureted systems are very sensitive to fuel line size.
