I just bought a 93 GT that had sat for a few years(2-4 years).

Exceptionally good condition.

It runs if you spray starting fluid or fuel into the intake. However it wont pump fuel.

I dropped fuel tank which is full of gunk. Going to replace the tank, pump, sending unit, everything.

I think the hard fuel lines along the rails are fine, I was going to blow them through with wads and compressed air to see how clean the wads come out.

New hard lines are expensive! Does anyone know a cheap source for them?

But what about the jumper lines? the lines between the tank and fuel filter on the supply side and the line between the tank and return hard line on the return side, Where can I find those? Rock auto has nothing.

Is there a better solution out there? Going all braided with AN fittings?

Pictures are inside of fuel tank along with the jumper lines Im trying to replace.

For the replacement of the parts you are looking for you might look at;

LMR or NPD

For the lines from the fuel Pick-up to the fuel filter they make repros but are not the same as factory. For those you might source from eBay or a Mustang specific place like MPS Auto Salvage.

I run this line, has worked fine.

Mustang 1/4" Fuel Return Line From Fuel Tank To Hard Line w/ Factory Connections (86-93) 5.0 MUR1017RH

Replace your rotted out fuel line in your 1986-1993 Mustang restoration project with this return fuel from Late Model Restoration!
lmr.com

I don't think the supply is available.


If you want to change to AN, you'll need to source a different fuel pump hanger like such.

Pro-M Racing High Flow Fuel Pump Hanger for 1986 – 1997 Mustangs! Finally, a real solution to the Mustang fuel pump hanger problem! The aftermarket has been selling high volume fuel pumps for Mustangs for many years. But until now, no one has addressed the other half of the problem... The 1/4”...

I recently refurbished my lines. The hard lines were still good enough to sand down the surface rust, clean em up, and back they went.
For the others, I bought nylon line off Amazon as well as the Dorman tool to put the fittings on. Worked like a charm, and no leaks! I also re-used the outer rubber hose that protects the nylon after cleaning them up.

What about the lines under the hood? It seems as though the hard lines turn into soft lines with no connections under the hood below the air filter

The hard lines sneak through the inner fender. Then the nylon lines connect to them (pressed on barb fitting). Then the other end of the nylon has the connection to attach to hard lines coming off the fuel rail.
The Dorman tool help get the new nylon onto the barbed fitting. There’s videos showing people using boiling water tI soften them and then press on, but the quality of the results have not always been great.

The fittings that connect to the fuel rail. Are those reusable?

Yes, I reused mine. That’s where that Dorman tool came in handy. Made getting the new nylon lines back on the fittings very easy.
