I am about to hook up my fuel line from the fuel pump to the carb and need to know, should I be using steel line or steel braided flex or does it make a rip. If it doesn't matter I just as soon use the flex and be done with it. However I don't want to start another Chicago fire in my garage or anyplace else.
Oh yeah, 350 chevy small block HO with Holly carb.
Either is fine as long as you DO NOT remove the braid on the flexible line and you use the correct fittings. The braid takes the pressure and the inner rubber is only there for sealing......IF you look at fuel hose (the rubber stuff from the parts house that says "fuel" on it) that hose also has a braid that is covered by a layer of rubber.

With a carb, you're only looking at 7 psi or less, so the braided line will work just fine.
Whatever you use will be fine, just keep it away from heat sources to prevent fire and vapor lock.
If you plan to do any drag racing at a strip where they have a decent tech department, you should know that you're allowed a maximum of 12" of non-metallic or non-metallic braided fuel line in the entire line from the tank to the carb. Short lengths are acceptable for connection purposes only, and cannot add up to more than 12" total on the entire fuel line run. NHRA-accepted woven or woven pushlock will pass tech also.
