Archived Bad fuel leak

[Lightninluke]

First hello. My 1993 W250, Cummins diesel, has a really bad fuel leak from the back side of the injection pump. Had a little leak for some time. Its getting much worse. I know I have to pull pump off. But I have no idea what then. Can anyone help or have had this problem. Thanks.

Rotery style pump.

There is a plate with an o-ring on it on the back side of the pump. The ULSD and time have finally disintegrated it. You can get a reseal kit for a VE pump pretty reasonable that has all the O-rings and seals, any Bosch authorized dealer can provide it.

Hi thanks, could you be a little more descriptive to what it is as far as the o ring kit. Thanks.

It is a seal kit or reseal kit, that is all. Any Bosch dealer should know what it is.
