My 98 VW TDI Beetle has developed a leak where the "top" cover of my injection pump. I got a new Bosch gasket set and the special triangle socket for the top bolt. Used brake cleaner first before disassembly. Took off the 4 bolts, carefully removed the black seal under the top cover of the pump. Cleaned both areas of the injection Pushed the new seal carefully into place. Slowly pulled down the bolts evenly so it sealed well then tighted the bolts.

I started it up and it was fine for a minute and then started to leak again. Took the cover off again and it all looks good. There are no scars or scratches on the sealing surfaces. ANY help would be GREATLY appreciated.

Thanks,
John:(
