is a Westerbeke
W30, AKA 4-91. Was running fine, but had an annoying fuel
leak from the pump.
I just removed the fuel
injection pump to reseal it, replaced the O ring between the housings as well as the other gaskets. I have reinstalled it and am having trouble getting the pump to bleed. I have an electric pump
which I can run independent of the ignition switch. I hear fuel return to the tank when the pump runs, I get fuel dripping from the bleeder on the rear (tranny side) housing as well as from the pressure switch bleeder on the front. However, when I crank it, I have no fuel coming out the top bleeder on the anti-stall device. I even removed the entire anti-stall (9/16" hex) to see if that would do it, but I get no fuel there or out the lines to the injectors, which I had completely disconnected.
Fuel hoses from filter are correctly connected, kill cable in correct position, throttle at half. Oriuentation of pump to crankcase is correct, but even if wrong, that should not prevent it from bleeding.
After fooling with it for a couple of hours in midday heat, I decided to give it a rest to adjust our respective attitudes. I am recharging the batteries overnight and plan another try tomorrow.
Anything I may not be thinking of? Possibly a stuck plunger? I have considered that I may have damaged the sensitive innards but I was quite careful and clean and the thing only assembles one way with everything keyed together.
