Thread: A legal fuel line for NHRA???

Tweet

....Hi all, I want to race my car at the drag races in August but I have a rubber hose for a fuel line running from my mechanical fuel pump to my Holley Dual Feed line. Should I make my own & if so what materials should I use. Or can I buy an already made one??? It's about 24" long from the pump to the dual feed line. ..... THANKS, Bill

Tech should be along sometime to tell you for sure, but if memory serves me right 24" of rubber is too long of a run. I'd either make one from braided or steel line.

Nope, that long a rubber line isn't legal or safe...Might want to go with a stainless or a stainless braided line. I've seen the ready made stainless steel lines that go from the pump to the dual feed line, don't remember who it is that has them though. Some AN-6 line with adapters on the pump and dual feed line would work fine, too. I'm sure places like Sumitt and Jeg's offer a package.

Maximum length of NON-METALLIC fuel line (from tank to carb) is 12". This must include all short pieces used for connecting fuel filters, etc.

You can make up some low-buck steel line yourself. Autozone has lengths of brake line you can buy right off the hanger. Gentle bends can be made by bending the tubing around any round object, such as a soup can or cooking pot from the kitchen. Then, connections to the pump and carb can be made with short pieces of FUEL-COMPATIBLE rubber line and some hose clamps.

The line can be polished with a Scotch-Brite pad and then kept looking good by spraying on a coat of clear paint.

Not everything on a car has to be high-buck.

....THANKS a bunch! Bill

\back in my sprint car days, we went crazy on weight savings one year before the instituted the minimum weight rule. We decided paint was too heavy, so we did the entire frame and cage in the same method!!!!

...Is there any reason why I can't use -8 AN hose & fittings??? THANKS, Bill

No reason at all, -8 will work fine Bill.

.....THANKS Dave, I'm going with the -8 an then. I seem to have this 'thing' that bigger is better...... Bill
