Stripped out fuel pump mounting hole

The box auto parts stores sometimes have kits a LOT cheaper than that. Or NAPA. Or, if you can get just the rigth tap and the right helicoil, then a pair of stout needle nose pliers can be sued to install it and break the tang off.

I'd use a helicoil, not the thread restorer IMHO; these bolts take some side stress as the pump operates and need to be very stable in the housing.
