Help needed with fuel lines.......

Post by 92wagon » Wed Jul 08, 2015 12:22 am

Hey all,

I just purchased a 91 Legacy wagon.. It has a fuel leak.
From what Ive seen after taking off the access panels in the rear of the car it seems like its the fuel lines going from the top of the tank... How much of an undertaking is this? It seems pretty straight forward but I'm looking for some advice..



Fuel lines in question....

you would need to completely drop the gas tank out of the vehicle to access any of the lines circled in red. Which is pretty much the most annoying thing to do on this car as it involves removing the rear subframe (I think I actually just unbolted it and let it hang from the suspension components). Lots of tools and patience are needed as a lot of things need to be removed that probably have never been touch.

The first time I did this it was on jack stands in a garage, so it is possible if you don't have a lift. I had to do this a few times in a car where they thought it would be a good idea to use a self tapping screw as a ground under the back seat, straight into the gas tank... I also thought it was one of these lines, until I dropped the tank and found the screw hole.

I felt like I would be able to snake them up through without having to drop the tank.. but I'm not completely sure.

I don't think you will be able to. Its been years since I dropped a tank ('05) and if i remember correctly, everything is so tight in there.

Yea.. It seemed really tight. I was just hoping it would have been a bit easier :(

So after reading quite a few archived posts I think I will replace the hard lines with some rubber gas line bypassing the hardline and leaving them in place.

interesting fix, hope that works. At least that will tell you if its the lines or the tank itself.

I'd still be driving my '91 wagon if I could have replaced the rear crossmember :( it was rotted and the fuel lines needed to be replaced as well-couldn't even snake them with access from the fuel sender and crossover pump :(

If you replace the hard lines with rubber, make sure you use fuel injection hose for the supply and return line. Regular fuel hose is not rated for the higher pressures.
