Hello all. A few days ago I noticed a puddle of fuel under my car, under the rear end. On the underside of the car, where the feed and return fuel lines go into the car, it was all wet. After wiping it off, I found it coming out of one of the gaskets. I was wondering what this gasket is called/part number so I can order a new one. Btw, its the gasket under the big washer. Thanks

 

I don't see the exact gasket you're looking for maybe you can spot it

I suspect most if not all of these parts are long discontinued.
