Fuel Pump Hammer Smack

The gas in my tank is probably ~6 months old at this point and the car had been sitting for around 2 months (without fuel stabilizer in the tank) while I am redoing its interior.

I was traveling a lot for work and when I returned and tried to start the car, the battery was dead. After charging it, I found that the car wasn't starting and traced it to the fuel pump. After a lot of poking and prodding with the test light I found that the wires to and from the pump were getting pretty hot so I gave the pump a few smacks with a hammer, as some orange gas was starting to sneak its way out around the hose (not a great color for gas), and it started right up and I let it idle for ~20 minutes while I added fuel stabilizer.

Question - the car ran great, do I need to dump the tank? Should I replace the fuel pump if it's working now (its only about a year old)? did the pump somehow rust shut internally (the tank is around 3/4 full with 93 octane fuel which probably has ethanol in it).
