    Hello I got a fuelpro 321 on my truck and I'm wanting to do a fuel filter change but not sure how to do it correctly since the filter is upside down

    Does the bottom have a fuel drain in it? If so, drain the fuel out and take the filter out.

    A friend had it - blow the whole system off and go with a regular setup.

    I looked at it - with my limited experience. I said - THATS GOOFY.

    My mechanic looked at and . . . changed it to a regular mount where the filter hung like it was supposed to - with the drain at the bottom.

    Myself I'd just drain it out, spin filter off, spin new filter on. Prime and go.

    Never made sense when I looked at it to have it inverted. I don’t see them often. Was there a reason for it?

    Maybe it's just mounted upside down. Just saying. I don;t really know.
