I want to replace my fuel lines with stainless braided lines instead of going through the work of bending new, hard lines. To my understanding, i just need to have the correct fittings, so what fittings would i need to use for my 95 GT?
Smaay
so you want to spend 5X the money for braided lines? you will need about 6 feet of -4 and -3 lines, then a -4 banjo fitting to fit the bottom of the fuel filter.

what is wrong with your OEM hard lines? are they rusted with holes? if it aint broke, dont fix it

Yes the hard lines are rusted bad and fuel is weeping out. I figured a thicker line, maybe -6, would be good to support a Supra fuel pump, because I plan to swap a 3sgte.

What about the fittings to the fuel pump? I'm looking at a diagram and it looks like theres compression fittings?

you can do that or make your own line. they sell the hard lines and rent the kit at autozone

ok if your lines are rusted and weaping, then you need to fix it. -6 is overkill IMO, and you dont need a Supra fuel pump if you are swapping in a 3S-GTE. NOW, if you are going to build the #S and make stupid HP then -6 will support that. Im just trying to save you money and prevent you from spending money on stuff you dont need.

when I designed a return fuel system for the 7th gen, I bought a 6 foot piece of 3/16 brake line, I used AN tube ends -4 and i used a flair kit to flair the ends for the AN fittings. this was good for the return line, the stock feed line was good enough for 550HP.

In my Supra I ran a 1/2 aluminum hard line under the car and did the same thing for my feed line. I think i used -8 at the tank then split it in the rail and fed each side with -6. I used the stock feed line as my return.

So I have to flare the ends of the original fuel line to use an fittings on them?
Smaay
yes. well you could get hose and use the barbed fittings and just clamp around the OEM lines. but if you want braided lines, then you need to flair them, just put on the collar first
