What can I use for fuel line fittings?
PTFE Lined Hose is the best soft hose you can use and generally has a braided stainless or braided nylon exterior. The PTFE liner blocks fuel vapors and slows the degradation process. PTFE Braided Hoses require Special Fittings.
How much horsepower will a 3/8 fuel line support?
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. The simple way to know is to install an electronic fuel pressure gauge. If the pressure falls as the engine RPM's go up you need more pump head.
Can you use brass fittings on fuel lines?
It is common to find brass fittings in the air brake systems, cab controls, fuel systems, engine, transmission, cooling and air tanks on a heavy-duty truck and they meet DOT and SAE requirements. Let's take a deeper look into why brass is an ideal material for this market.

What size is standard fuel line?
Typically, these 1/4" and 5/16" line sizes are in use for low flow or OEM systems, but are commonly used in high performance applications for pressure gauges as well as plumbing between the Regulator and Intake Manifold.
What size fuel return line should I use?
The Fuel Return Line should be at least the same size, or one size larger than the supply. Make sure there are no sharp bends or kinks. The return line should direct fuel close to the bottom of the tank and away from the pickup.
Does fuel line size affect pressure?
Shows the relationship between measured pressure drop as a function of flow rate, for four different fuel lines (two different sizes at two different lengths). Every fuel line experiences pressure loss depending on fuel line length, and fuel flow rate.
Do I need bigger fuel line?
