Okay so I am gathering all the parts to swap my 1980 coupe over to efi. Couple questions I had about the fuel system..

For the fuel lines coming from the tank up to the front of the car, do they have to be out of an 86-93 Mustang, or are there other cars that use the same fuel line routing such as the lincoln or t birds? Also can I use my same gas tank or do I need to find one out of a efi Mustang? I am pretty sure the 2.3 L efi mustang gas tanks are the same so that won't be a problem to find if I need to get one. Thanks

As far as I know, the lines need to be out of a stang. Undercarriage of tbirds aren't going to be the same. The gas tank should be the same as well

Probably not the answer you are looking for, but I would source a wrecked 89-93 5.0 car and swap EVERYTHING. Engine, wiring, fuel lines, gas tank, suspension....

I had to replace the fuel lines on my 90 GT and searched the boneyard for a replacement. I checked the T-birds and Mark VII's and found that the fuel lines are not the same. I got lucky and found a V8 mustang that had decent lines on it, so hopefully you will too. But I don't think new lines are all that much either. Good luck.

v8 explorers are another place to look, but not sure if the fuel lines are the same or not.

What about a braided line? How hard would that be to do and how expensive is it? Ive never used it before so not sure how it works exactly

You will need to run some new fuel feed lines or braided hose. The 3/8" aluminum tubing works well, but you will need a flaring tool and bending springs to fabricate the lines. Braided hose is easy to run and route, but is much more expensive. It is about $3.50-$4.00 a foot plus the end fittings, which are $3-$4 each. Fabricating hose assembles can be difficult, but anyplace that makes hydraulic hoses can do it for you for an extra charge. See Amazon Hose - Rubber, Hydraulic and Industrial Hose - since 1919 for more information.

For stainless steel braided hose and fittings for automotive use:

See SummitRacing.com

stainless steel hose - JEGS High Performance

See http://www.aeroquip.com/pages/performance.html for more information on High performance automotive hose products

The fancy red & blue AN fittings require a 37 degree flaring tool. A standard automotive or household plumbing tool is 45 degrees and cannot be used with AN flare fittings. If you do, the flare is subjected to too much stress when the fitting is tightened, and is likely to fail or leak.

See Industrial Supply Equipment from MSC Industrial Supply , McMaster-Carr or for the flaring tool you will need . Prices start at $81 and go up
