I have a 1960 Case 140 W baler that has a 4 cyl air cooled Case engine on it set crosswise. It has a fuel pump to pump gas up into the carb from the fuel tank down beside it on the frame. Anyway, the pump quit. Cant find another, nor one that crosses. I have a couple here, but they say the foot, the part that goes against the cam in the engine is too wide. Im wondering, if I could grind off a bit on either side and use it or not. Thanks for the thoughts.
