Fuel Pump Leak.

I noticed last weekend my fuel pump drips gas at about 1 drip per 1-3 minutes. I had really old tubing going from my hardline from the tank to the pump so I replaced that today and the tubing and fuel filter going to the carb while I was at it. Once I replaced it I started her up but the dripping continued. Do I have a bad fuel pump and should just buy a new one? Or do they have any types of gaskets that can be replaced on them that would be causing the leaking?

I think there is blow-by hole on mech fuel pumps to let you know it blew the diaphragm. Water pumps have this also but for the seal. Check your lines again but my money is on the pump. For ~ $20-$25, it is worth it to get one and eliminate the pump as the problem.

Check your oil for gas, if you blew the diaphragm. Sometimes gas will blow through and get gas in your oil.
