Hello .. thanks for the donation .. much appreciated
I'm guessing you had the pump changed and not the filter ?? your post is not realy clear ?? there is a filter on the tank and a secondry filter !! the filter could be your problem .. change the secondry filter mounted on the firewall/air cleaner .. also add a good fuel cleaner to the tank to clean the lines and injector's !
A mechanical pump is mounted on the right side of engine block. Camshaft eccentric drives pump. Pump pulls fuel from the fuel tank through a primary filter. The fuel is then pumped through a secondary filter, mounted on firewall (pickups) or rear of air cleaner (vans), and to the injection pump.
FUEL MANAGER/FILTER ELEMENT
Fuel filter is mounted on rear of intake manifold, under air cleaner. Remove fuel tank cap to release pressure or vacuum in tank. Remove filter element nut. Remove filter element by lifting straight out of filter housing. See Fig. 8. It is not necessary to drain fuel from filter housing when changing filter element.
