Hi All , Can anyone tell me the exact dimensions of the big O ring that goes into the rear of the pump ( Bosch VE ) on a '95 300tdi ? I have diesel dripping from underneath where the square plate joins onto the pump body . I want to buy a Viton O ring , can probably find one locally if I knew the exact inside/outside measurements . Thanks , Gerry .
 
I'll probably go with that one for now . I have plans for a wvo/petrol blend later on , but I will do a complete reseal job using as many viton parts as I can before that , especially on the front seal . Don't want diesel spewing over my new t/belt ! Thanks for the help .
