NEED HELP,FUEL PUMP BOLT ISSUE,LEAKS OIL

Grease in a tap works well. I’ve done a spark plug thread in a pinch for a coworker once who cross threaded a plug at work one evening in a Nissan four. I was able to get a standard tap back through it and got full chip recovery with the plug facing straight down into the chamber. I like using the tap wrench with a drill bit and Heli-Coil while blowing air (shop vac reduced to a heater hose set to blow in the pump arm opening) from the backside.
