I have seen aftermarket and stock ground pins that allowed too much travel and resulted in a fuel leak around the afc pin.

I have ran the pin before but its never leaked till I turned the fuel screw a little?? It was leaking out that hole like there was no resistance on it at all.

Updating my old post. I had put earlier that the leak stopped when the factory pin was reinstalled. Its leaking again. Does anyone know what seal/o-ring could be causing this. I was thinking that the little rod that rides on the fuel pin has a o-ring but cant remember. Looking down through the top of the pump that rod dont move anymore when you open up the fuel linkage.????

There is an O-ring on that little rod, and it needs replaced. It's not that hard to do if you've had your pump top off before. The hardest part for me was getting the two little pressed in ball bearings out so I could get the afc lever out of the way, and get to the o-ring.
