    Default D2 5U diesel in oil

    Hi All,
    I have a d2 5U that is getting diesel in oil.
    Assumption is that the injection pump to filter housing needs to be replace.
    I found this gasket part number (4F5148)
    I have not found the governor to pump gasket in my parts book?
    Should I re-seal the transfer pump at the same time?
    My s/n is 6076, does it have the rear o-ring seal?
    thanks for any help!
    Hope to tackle this project in a couple weeks

    These are the gaskets you'll need for the D2...
