    There is a fitting after fuel filters were fuel line screws into the block. Looks like a gic/pipe tread hyd fitting but is actually a check valve. Take it apart. Surprising how much junk gets in that check valve and limits fuel flow

    There is all so a fuel filter/screen in top of pump under small tappered cap. Then if it uses spin on fuel filters check for crack in filter housing head. Seen this many times. Pulls some air and looses power
