What type of fuel line should I use?

[Supersport350]

My Camaro is nearly ready for the cruise season, but one of the things I have left to buy is fuel line. I have a complete Aeromotive system (A1000 pump, 2 filters, and regulartor) and a sump welded to a stock gas tank. I have 10AN fittings at the tanks, filters, pump, and into the regulator. From the regulator I will have 2 6AN lines to the Dominator carb, and an 8 an return line.

I have all my fittings for the pump, filters, and regulator. I still need to buy fuel line and fittings for all my hoses. I really have ZERO desire to work with stainless, as I don't care to buy the tools to crimp the lines, don't care to get stabbed by the braiding, and don't care for the weight. I do plan on drag racing the car, so need to meet NHRA requirements. I am looking at this nylon braided hose, which is lighter, but cost a bit more than stainless. This is what I'm leaning towards. Hard lines are an option, but then I need to still have flexible lines going to the tank, filters and regulator. The savings were about a wash by the time I added in the extra fittings I would need to transition.

Any recommendations? Any have experience with these twist-lock, push-lock, or other types of fittings? Any help would be greatly appreciated, as I hope to place another order in the next few days, for either the line, fittings, or possibly throttle bracket I still need. Thanks!

Just got off the phone with Jeg's. I think I'm going to go with their Pro-Flo Nylon hose. Anybody have any experience with this hose, as far are installing the fittings? Will I need their hose/cable cutter in order to cut this stuff?

Haven't used the product in question but I have worked with lots of SS braided Teflon-lined hose. Works great but does have the drawbacks as mentioned.

I will caution you not to use hardware store ferrule fittings ANYWHERE in a fuel system. Those are no longer US made and they'll fail and cause engine fires (I have a Camaro to prove it).

well, you do it in stainless and you never will do it again. the flaring is really not that bad and you dont have to worry much about anything damaging it or heat like the nylon.

as far as the hose cutter, they probably need really square ends to work properly so thats why they are recommending the cutter.

I've gone to the black nylon braided (Earl's) pretty much everywhere in the fule system with no observed issues. I have kept SS braided where there is potential exposure to road hazards. I had a hard line get cut by what I think was a smashed paint can a few years ago so I ut with the fun of the SS. I cut mine with high tooth count metal Sawsal blade and get very clean cuts wrapping the line with blue tape first. i support the hose in the vice with plastic vice jaws and a wooden dowel inside the hose.

In the camp of hard line from pump to regulator. ^^^^... use a cutter that rotates around the line, and you'll eliminate any dimpling or crushing of the hard line.

Most of the rubber lines break down over time, or "breathe", I like Teflon lines, you can run any fuel they dont break down over time, and it wont stink up the house from Breathing. The brading wont stab you if you use the cable cutters it cuts clean and flares out where the fitting goes, it works better than any other way I have ever cut it.
