91 Grand Marquis Fuel Line Leak

Pulled the car in the garage then noticed a small puddle under the drivers door...gas! It only has 112,000 miles.

Didn't crawl under but it feels like it is leaking under one of the clamps along the frame. Is there an easy fix for this?


Small rant: I had a 85 Grand Marquis and the brake line rotted away about the same spot. I won't mention the frame on this vehicle, you could stick your hand right through it.

Thanks

You are going to have crawl under there and inspect further. If it's the aluminum line that is cracked, the hole line is going to have be replaced. It maybe coming from the fuel filter as well, but let us know mor details.

I've found there is a fuel line on both sides. The filter is on the passenger's side, this leak is on the drivers side so I think it's the return line.

I thought I could cut out the bad part and use a rubber line but was told no because of the 30-60 pounds of pressure.

However, it looks like they have rubber lines between the steel line and the tank, can't a person buy some of that whatever it is?

Here's a couple pictures, it's leaking to the right of the plastic clamp.

One guy told me to cut out the bad part, flare the lines and add a new piece. I don't know, the whole line looks pretty ugly me.


I can't imagine trying to snake a whole new line into place.

I own a 91 Grand Marquis (my daily driver), 85K, since new, and have dealt with three separate fuel line leaks along the frame because of corrosion. There is no way to elegantly replace the whole line. Ford basically installed the fuel lines to the frame then built the car around it!

You don't have to go through the trouble to make flared ends for the fix. You can cut out the bad section of line and install a new one using compression fittings, like plumbers use.

Though my car is regularly rustproofed by myself every few years, the fuel line corroded in the "shadowed" part of the rustproofing. This time I made sure the entire line was covered 360 for complete rust protection. I recommend the same for yourself. It's either labor spent up fornt on rustproofing or labor spent later on rust repairs.
