    Intake pump question

    Does anybody know what the exact difference is between an early fuel "pre-pump" and the late ones?

    Browsing through realoem I see pre 9/83 used 16141179414 and 16141179415 from 9/83. And 16141184022 used from 9/87 and up.

    Wondering if 022 would work in place of 414 temporarily?

    Thanks....
