Title: advance mechanism leak - how hard to repair?
Post by: derekp on July 25, 2011, 09:39:17 am

my 92 jetta seems to be leaking fuel where the advance mechanism goes into the pump body.
I cant see it too well - dont know if theres other things on that side of the pump that can leak. (I'll be looking at a junk pump I have at home to see what else is on that side of the pump)

I wonder if anyone can tell me how hard it is to replace the seal/gasket that the advance mechanism needs?

Also - where can I get the appropriate seals/seal kit to do this repair with.

thanks!

Fix is easy to do.  A couple of O rings. One on the shaft and one in the cover if I remember right.  If that is all you need you might find them at an auto parts place.  Just have to be able to take the diesel fuel.  I did a complete rebuild so I got the entire 30 dollar kit and the rings were in that bunch.  If I only needed the two I would be shopping around.  Diesel truck repair shops?
