Fuel Line Routing

[1moretoy]

Hey all, I'm trying to figure out the best way to run my fuel line. I'm running -8AN (1/2") stainless braided PTFE. I also have US Cartool subframe connectors. Is there any issues running it along the outside rear frame rail to along the subframe connector to the front? This would be similar to the factory lines but braided instead of hard lines. The other option is to run it inboard but that puts it closer to the exhaust. Let me know your thoughts.

Thank you,

Should not be a problem at all. Factory path is perfect.
Here is a great article which shows the factory fuel line path with a return line.

Have you considered running a return line to the tank? It is easy to do if you repurpose the existing hardline as the return and use your braided line as your supply.
Run the braided line parallel and you will have an excellent system.

All the factory lines are gone and I'm running a returnless system. Being braided lines I wasn't sure if there was added concern if an accident happened side impact, and leaking fuel. Forgot to mention I'm also mini tubbed so there isn't a gap between the frame rail and inner fender to conceal it.

You know as simple as this is....I'm putting in EFI right now and I NEVER thought about using my 3/8 factory style line as the return. That's a great idea and gives me a nice run to mount my braided to and since there's no pressure on it I don't need to worry about leaks, AN is overkill. I think I'm gonna do this, thanks for this!!

A few photos of the EFI rubber fuel supply line (3/8" ID) routing alongside the factory steel 3/8" OD line repurposed as the return line.

Nice. I'm running braided line, but I'll be doing this for sure. Just gotta grab some different fittings now...

Any reason I shouldn't use a tee over a wye? Dual pumps feeding into one line. I have a wye, but routing looks much cleaner and easier this way. The PTFE isnt as forgiving as regular rubber hose.

Fore Innovations makes a Y that has female -12 ORB ports with the duals running parallel. You would buy the fittings that adapt -12 ORB to -8 (in your case).

What's your plan to drive the dual fuel pumps? Can't see it in the pictures, but do you have a regulator as well?

Yeah, I Have fore fittings already, they make nice stuff.
My plan for the pumps is to run PWM. Tapped performance makes a nice wye harness so I can run two factory fuel pump control modules. When running a pwm setup, no external regulator is needed. With the right connectors on the pumps, it should be a plug and play set up.

I'm also running an over pressure safety kit as well from protouringstore.com This will bleed off any built up fuel pressure cause by heat preventing hot start issues. I had Rick's tanks drill and extra hole for the jet in the fuel pump Hat.

When you have a non-OEM fuel pump running via a pulse-width-modulation (PWM) controller such as a factory Fuel Pump Control Module (FPCM) or an aftermarket one like VaporWorx, your fuel system can build up excess fuel pressure since there is no regulator. This excess pressure can rise so high...

Awesome - looks like you know what you're doing. I said regulator, but I meant it for use in the over pressure safety sense. Looks like we have basically the same build. I'm doing a Redeye with Tremec Magnum in a 70 Cuda.

I have -12 braided line run along the outside of my frame connectors with no issues from the fuel pump to my fuel log.
