How big is a fuel line? Most stock applications came with 5/16-inch fuel line, but for many street vehicles and mild race applications 3/8-inch (AN 6) fuel line is a good upgrade. High performance applications and racers using alcohol will use 1/2-inch (AN 8) fuel line.
Is 3/8 fuel line big enough?
A 3/8”id fuel line can easily support 600 HP given sufficient “pump head”! Given a big enough pump a 3/8” steel line could support 1000 HP. ... If the pressure falls as the engine RPM’s go up you need more pump head. More pump head can be achieved with a bigger pump, higher pump voltage and/or increasing the line size.
How do I know what size fuel line I have?
Place the top of a 1/4-inch wrench with an open end over the fuel line. Slide it carefully over the line so that it fits snugly against the tubing. Read the wrench’s measurements to determine the diameter of the fuel line. Place a caliper over the fuel line if the wrench did not give an accurate reading.
Can you use 3/8 line fuel line?
Use it steel, 3/8 line is 3/8 line, brake line is probably just higher quality (cost you more) because it has to take MUCH higher pressure, but it will work fine for gas line , make sure as others said that the rubber hose you use IS GAS hose.
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 .
Which fuel line is bigger 3/8 or 5 16?
a 3/8 line will carry 44% more fuel than a 5/16 line.
Can a fuel line be too big?
Registered. Actually you can have too big a fuel line...if the line is too big and your car accelerates hard yet you don’t have a massive fuel pump, you will have the additional weight of the fuel in the line pushing back and fighting the fuel pump which can cause cavitation.
Is fuel line size ID or OD?
Tubing is OD (outside diameter) and Pipe is ID (inside diameter) . So the easiest way to tell the size of your fuel line, which is tubing, is to use a combination wrench. Whichever one slips over snuggly is the winner.
What diameter fuel line should I use?
Most stock applications came with 5/16-inch fuel line, but for many street vehicles and mild race applications 3/8-inch (AN 6) fuel line is a good upgrade. High performance applications and racers using alcohol will use 1/2-inch (AN 8) fuel line.
Which fuel line is the return line?
The vapour-return line normally runs from the fuel pump or the fuel filter to the fuel tank. This vapour-return line is connected to a special outlet in the fuel pump. Any vapour that forms in the fuel pump returns to the fuel tank through this line.
Are brake lines and fuel lines the same?
The only difference between fuel and brake line would not be in the compositin of the metal, rather, the diameter of the line. Brake line, being of smaller diameter, would not allow the same volume of fuel to flow , potentially leading to fuel starvation.
What is the best fuel line?
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.
Where can I run fuel lines?
The fuel lines follow the frame connector toward the back of the car, then loop over the top of the connector and along the inner side of the rear subframe to keep them away from the wheel and tyre. The lines connect to bulkhead fittings at the leading edge of the gas tank.
Does fuel line size affect pressure?
Every fuel line experiences pressure loss depending on fuel line length, and fuel flow rate . ... This is why gauges typically use 3/16′′ or 1/4′′ line size, as they will not affect performance due to pressure loss. Now, we’ll examine how fuel flow rate is affected by fuel pressure drop in a carbureted system.
Is 5/16 fuel line big enough?
Yes, just make sure you have enough pump .
What size is #10 fuel line?
