    Any suggestions on prepping the surface before I rattle can some western red on the old pump housing? Should I primer the surface first? Never really painted cast aluminum....

    clean it with something that does not have a residue to get the oil off....enamel reducer, precleaner, brake cleaner

    Yeah I have got that part covered.... I was wondering if I need to primer the components, or will the western paint stick just fine?

    Iv painted a few.
    Iv used primer...and others I didn't.

    Lightly scuff up the aluminum with a scotch Brite pad. Clean well. Let dry. Thro on the paint.

    If you are gonna use primer..
    Probably should use self etching as it'll bond to the raw metal better

    After epoxy primer, paint you could use clear with harder don't forget to wet sand and buff

    there are aluminum specific primers if you took the housing down to bare metal. if it still has the old paint on it, then just paint it. the only reason for a primer is so that the paint adheres to whatever material youre painting. also so that you don't end up with bleed through, like if you were painting wood, the oils in the wood will bleed through if it is not primed properly..
