Hello: I have been having a problem with a 2 piece fuel pump (AC) on my aluminum big block 1969 Camaro. The first one I used leaked engine oil from the vent holes. I sent it out for rebuild, re installed it and got about 3 miles before engine quit. I sent it back for repair and when I got it back it leaked fuel. The rebuild guy had left the screws loose and striped out a couple. I got a new/rebuit pump from Heartbeat city, installed it and the same oil leak appeared. They replaced it and now I'm leary of installing it. My friend at the engine shop gave me a special gasket which blocks the engine oil from the fuel pump. The instructions from the gasket say to grease the pump rod and recomends putting a grease fitting on the pump. I don't really want to do that.
Has anyone had any experiance with these 2 piece pumps? Did they all leak oil. I think it was an over the counter perforamance part and the only production car it was used on was the ZL1. I tried to get a different pump (not 2 piece) but the line to the carb would interfere with the smog pump. I tried pumps from other big block Canaro apps. but they were all the same.
Thanks for the help:
