My car's leaking fuel at the tank: how to remove the pump shield...

[MarkRobinson]

My car's incapacitated across the street on a lift: leaking fuel while the car's running at the bottom of the tank, hidden by the stone shield that, I assume, hides the pump.

Anyone know how this shield comes off? Shop can't figure it out. Any idea what they're most likely to see?

Time for a new shop...

There's a bolt that holds the strap containing the cover. Clark's has a well-written procedure:

Mark:

What year and make is your car?
If 944n/a late, you should see a strap holding the entire gas tank cover on. Using a long extension you remove the entire cover. Then, to remove the fuel pump from the bottom of the cover you loosen the large hose clamp via a screw. Most times these things are rusted, so you may have to use WD-40 to get it to move.

So, yes! The stone shield does hide the fuel pump which is held on by a large hose clamp. The adjustment screw, for this large hose clamp, on my car was very hard to see. The factory people placed it at the bottom near the cover, so it took me a good hour to figure that out. Also, if the stone shield has road dirt on it, or if it has been covered with undercarriage sealant (usually black) it will be a little difficult to see the hose clamp on the outside of the stone shield.


My best guess for the fuel leaking is there is either a seal, or seals, gone bad, or one of the hoses needs to be replaced. If I remember correctly, there is one hose going from the bottom of the tank to the fuel filter and another hose going from the fuel filter to the fuel pump. Bango type fitting there.

Hope this helps.

hi, the most likely scenario forthe metal fuel tanks is that rust has attacked the tank behind the securing strap, as that band has a foam anti-vibration inner surface that helpfully holds water against the tank..
You can repair it by loosening the band whilst supporting the tank, and use petro-patch to seal up the hole. Better is to get the tank out, a PITA, and have it sealed internally, or replace it.

This happened to me last year after filling up the tank! Quite a mess! In my case, the little rubber hose from the tank to the pump had cracked. Hopefully, that was all you needed too. I have to agree with Scooby though. I don't remember having great difficulty in discovering that the strap is bolted in on one side. Let us know what the result was.

By the time I got home my massive fuel leak had stopped. I put the car up on the lift anyway & pulled the lower pan to look for obvious signs: nothing obvious.

I'll plan on a new pump & feed hose & will rebuild all the flexible fuel hoses under the car in a month or so.

Odd: Porsche lists the same pump for turbo vs NA.
