Jim; Did you add ref #57 part #319340 extension, impeller housing to exhaust housing. That seals the impeller housing from sucking exhaust gases. The top of the impeller housing would normally butt up against the exhaust housing without this piece. That might be one explaination? Of course the water pump needs to be in good shape to pump further, but that goes without saying. Mighty small pump, though. Don might have a better idea.
