not had anymore problems with the pump. but i just tried to fix the leak at that screw but it didn't help, actually i made the leak worse so i may not know what i am doing. i took the screw out and wrapped the tape around it. when i turned the pump on it leaked worse so i took it back off. the screw is like a wing screw(i guess that's what you call it) and it leaks from the middle of the screw. can you tell me what i have done wrong or what i can do to fix it? thanks.
