      Fuel line recommendations...

      Got a second-gen Camaro with full Speedtech Extreme suspension, LS427/570, T56, Rick's Tanks Restomod with ZL1 fuel pump, and VaporWorx PressureWorx ZL1/Universal PWM Fuel Module Controller. Gotta work out fuel lines. I spent some time on the phone with Carl from VaporWorx, which turned out to be an invaluable call, and he gave me some great recommendations. I'm just looking to get the hive mind's feedback as well. I was recommended hard lines all through the middle with flexible lines on the front and back. I spoke with Speedtech as well and they do complete flexible lines through a lot of their cars. Some of the vendors I was recommended were Fragola, Goodridge, Classic Tube, and Pegasus.

      At this point, the only thing I know is I'm using AN6 lines. I like the idea of bending my own hard lines, but I also like the idea of an easy install with flexible lines. I need to figure out if I'm doing flexible lines entirely or a combination of flexible and hard lines. What are you guys doing out there? Which products are you using for your tubes and fittings? What else do I need to take into consideration? Any and all feedback is very much welcomed.

      Thank you!

      I’m in the same spot as you. I actually just ordered my fuel system from Rodney at Suspension Geek this week. Although he’s a suspension business, he is also a Holley dealer.

      I ended up going 3/8” aluminum line which is equivalent to 6AN.

      I use 3/8 nicopp hardline. For the flex I use Holley Vaporguard hose and fittings. Not a fan of Teflon lined braided hose.

      I’ll look into nicopp as an option. Teflon-lined braided hoses have been a consistent recommendation, if I was to go flexible. Why aren’t you a fan?

      Was it a pre-bent kit with fittings or was it more of a raw materials thing and you’re bending your own?

      Its stiff and kinks easily and I donít care for the look. Vaporguard has a nice OEM look and black fittings. Itís also easy to assemble.

      I used nicopp 3/8” line along the frame front to back. Then used the vaporguard hose and their fittings to connect to the hardline. Nicopp is pretty easy to use and it’s cheap. I got 25’ from Amazon for $50. I would recommend since it’s your first time making lines (like me) is to order some 3/16” nicopp line to make a template. The 3/16” line is dirt cheap on Amazon I’m talking under $20!

      The reason I recommend making a template is because I ran my line then didn’t like it so I bent it back, ruined it so instead of spending $50 mistake your at $20. Also the 3/16” line is much smaller so it’s way easier to work with. In the end you’ll have a great template for the 3/8” line. I used about 10’ of the 3/8” line for fuel.

      The rest I’m using to run trans fluid to the radiator/cooler. For trans fluid cooler lines I’m also using the same 3/8” nicopp lines along the frame rails then using the Mr. Gasket push on hose with their fittings for connecting from trans to hardline then hardline to radiator.

      Touchť..... A little pricey for the likes of me. Iíll stick with the Vaporguard.

      I would be careful with the aluminum line... most is not rated for the 58psi rated fuel pressure.

      Also 3/8" is marginally small. I would use -8 line.

      My vote is stainless braided Teflon. Easy to route, indefinite life span, impervious to chemicals & will never rust.

      Earlís low-pressure aluminum lines are rated to 100psi and not that expensive.

      I really like the idea of bending all of my lines. If I decide to that, I really like this idea of building a template from smaller/cheaper material first. Looks like a cheap way to gain hands on experience.

      Question on hard lines. There's seems to be a handful of popular materials out there. Steel, stainless-steel, aluminum, nicopp. Other than the obvious strength differences between them, why would one be preferred over the other? Do any of them have certain fuel restrictions?

      I bought a classic tube 3/8Ē metal fuel line and used tube to AN adapters to push lock hose for my connections at the tank and engine. Worked great! The only bend I had to make was in the engine compartment. I bent the line at the stock frame rail connection to route up behind the engine,to better conceal the line.

      I wouldn't use aluminum with any fuel that contains ethanol. I like NiCopp because it is easy to bend and flare and is non-corrosive. I also like how looks.

      Has anyone considered running the PTFE line for hotrodfuelhose? looks like an easy option

      I've used all those materials. All will work fine.

      • I prefer nicopp: it's easy to work, and bends and flares easily. It comes in rolls, so you have to work a bit to make the straight sections "straight". Still, I don't use anything else anymore.
      • Aluminum comes in several alloys and stiffness, from the completely annealed rolls you get from Summit/Jegs to the very stiff sticks you can get from McMaster-Carr. I've had success with all of them, and prefer to start with the straight versions.
      • Steel rusts, so you need to paint it or coat it after it's been bent to shape.
      • Stainless looks nice but is a real bitch to flare, and often cracks at the flares when used for brake lines. It tends to seep through flares in general too.
