4025182 was the Cummins part number on the plastic bag mine came in last week. I still got the bag in the garage and just went and looked at it. Royal is correct... just thought I'd double check for ya. Schied sold me mine along with my new lift pump. They said I might need it and I did. Only thing was they didnt tell me I 'd need new banjo washer seals. I used the old ones and they seem to not leak. I always like to put new stuff like that on but I didn't know I'd need them till I took it apart at 10:00pm.
