You would use the kit for the methanol pump or regulator, depending on which one you are referring to.
I suggested the E85 hose because it holds up better to the ethanol blended gasoline made today. PTFE holds up even better, but requires specific hose ends and costs more.
I have switched all my regulator diaphragms over to GFLT versions to extend service life. As soon as I use up my current supply of carburetor accelerator pump diaphragms, I will be switching them as well (I typically replace them every year).

Thanks for clarifying. You're not joking about the diaphragms on the accelerator pumps. Couldn't figure out why my car ran like garbage one day and it turned out the accelerator pump diaphragms were hard as a rock. Now have the light green ones. The additional alcohol in today's fuel screws with small carbureted engines (pressure washers and generators in my experience) as well.

I can't believe how small the stock fuel line is on my 82 GT. It doesn't look like it would feed a stock 4 let alone a v8. If I had realized just how small it was I would have replaced it years ago. Did all year fox bodies come with that small a line? Fuel injected cars must have been bigger.

Nope. 5/16".
At 40#, the efi cars can push more fuel through the same size line than a mechanical pump can suck through it.

Can anyone see any issues that need attention before I button everything up? I know it's probably not ideal but very little I do is, I'm more concerned with will it work and safety issues right now.

That top pic's fuel regulator and fittings just above this posting sure are close and above the headers ...

Closest to the headers is about 2" where the fuel line comes out from under the car. Everything else is 6" or better Do you think that will be a problem? The old fuel line was run through the same spot. I have some header wrap I cam put on it if that would help.

It just makes me nervous from the pic directly above the headers because if a fitting got loose it could be disastrous!

Hmmmm you have a great point. That never dawned on me until you mentioned it. Guess it's back to the drawing board under the hood.

This look a little less nerve wracking? Sure does look less cluttered. Problem is now I have to order more fittings. I've averaged about one order a week to Summit since I started this little fiasco.

....and yes I know I need to put the fuel line into the side port on the regulator not the end.

Got it all together and the highest pressure I can get is 4 lbs. No leaks that I can see. Is this normal or did I screw something up?
