    Great pics so where is that pump located on engine and it looks like a gear type pump and you just take cover plate off or do you have to take off pump complete?

    So what fuel pump had the loose gear the main pump ? It wouldn’t run with no drive on main pump ? Is it the lift/transfer pump ?
