Default Fuel leak in a fo fo

Asking for a friend who recently acquired a 944, which had been sitting for a long time. It's got a leak in the fuel line by the gas tank. I suggested rather than just patch, giving the age and unknown condition to replace the whole line. What sort of an ordeal is he looking at? Any tips, suggestions I can pass along would be greatly appreciated.

The pump, filter and some shortish hoses are back there, possibly under a cover. IIRC, they attach between the tank and the metal line that runs the length of the car. I would check the parts in the back first. Wouldn't surprising to find some leaking at hose clamps on now dry, shrunk, and hard tubing. Replacing all the lines might be overkill.

Very true. The cost of the replacement lines would exceed the value of the car!

be sure to check the fuel rail in the engine compartment.. no point fixing the back and then. bam.. gas leaks on a hot engine!

Thanks so much guys. Though I can muddle my way through the mechanics of an early 911, totally clueless as to a 944. Was thinking maybe Porsche threw in a fuel line like it did with the 80's Carrera that had a disagreeable habit of disintegrating and causing a car-b-que.

X2 on checking clamps and hoses first. Fuel rail is also known issue.

You didn't say what year it is and it makes a difference as the early cars have metal tanks and the later cars (85 1/2 up) have plastic ones and the lines hook up differently to the fuel pump. I have 2 early parts cars currently behind my garage with non leaking tanks and parts if he needs something. The lines can be a pain to get off if they are corroded since ummmmm heating rusted stuff back there can be ummmmm life threatening. I have had to cut some off and replace the end fittings. BAT (and others) make these nifty metric compression fittings that will replace just the end of the fuel line if need be so you can just replace the old stuff with new stuff.

I had to replace a rubber line or two back there some years ago (I don't remember the specifics) on my '87 because of a fuel leak. It wasn't really hard or expensive to do.

Depending on the year/type 944, 944S, 944S2.... this guy makes custom kits to replace all fuel line rubber. As most of these cars are 30 years old his kits make a lot of sense to spend a little time and replace all the little hose bits. Link at Pelican http://forums.pelicanparts.com/porsc...-line-kit.html

Hmm... glad you guys brought up this issue. I have been smelling gasoline every time I go into the garage. Looks like my 944T must have a gas leak too. Like to know which hoses ended up replacing.
