    Joe,
    I replaced the fuel pump as you suggested - no problem at all - stopped the engine at TDC, secured the push rod with a bolt and replaced the fuel pump - only problem is I needed no pressure at all to seat the fuel pump - just went right in. So any suggestion as to what I have done wrong and how to correct it - I don't want to crank the engine if the fuel pump is in incorrectly.
    BTW - I have attached a picture of the old pump - it has 2 holes in it that gas was dripping out of - the new fuel pump does not have those holes in it - any idea what those holes are?
    Thanks ,
    Joe

    The holes are vent holes. The new pump should have some sort of venting system, but it might be that they now use some other venting system.

    The side of the pump that the holes are on is the "dry" side. However, when the diaphragm fails, fuel from the "wet" side infiltrates the "dry" side and comes out the holes.
