Hey guys,

Been a long time since I've posted... I've been working like a fool unfortunately.

First off, instead of grave digging my old '87 Head Gasket Curse" thread, I'll just post an update here.

As I posted in that thread, the culprit was definitely a leaky head gasket which I had replaced, but turned out my oil cooler seals were also shot.. so I got those changed out as well. Been driving the car all year and all of thoseU problems have subsided. It's been great actually getting to enjoy the car.

UNTIL....

Fuel started leaking near my rear passenger wheel.

I started noticing a strong smell of gasoline about a week ago. I got under the car and noticed a drip of fuel from the filter or possibly the hose above it near the rear passenger wheel area. Drips about every 15 seconds after car is shut off. My fuel gauge isnt dropping noticibly, but still I've parked her and trying to figure it out.

Visually, the gas is dripping from the little rubber bushing thing on the brace holding the filter. The crazy thing is I've tried to inspect the lines above and below filter as far as I could and they are dry. Could it be the filter itself? It does look pretty wet.

Here are a few pics of the area I'm talking about:







Appreciate your help!

That's not the filter (the filter is located under the hood). It's the fuel pump, and they can spring a leak from the end that they are put together from, or the fuel line fittings on that end.

My guess is that you're going to be in the market for a new fuel pump after you release the mount and pull the pump down to get a look at the source of the leak.

Doh! Don't know why I was thinking filter instead of pump.

I'll try to get the mount pulled down within the next day or two and report back.

Thanks for the reply!

Probably easier to remove the road wheel and have a look at the pump connections that way?

Had a similar fuel leak in 944 just a month ago. It turned out to be the pump itself. The pump had microscopic cracks on its body. It started to leak when the temperature hit -20 celsius.

If it turns out to be the pump, I have the best price going on an OEM-equivalent pump from Walbro.
$109 + shipping
