So I went ahead and removed my fuel screw / lock but from my AFC housing with it installed on the pump.

I went to screw her back in and only got 50% threaded before it stopped. I tried a few times.

I’m referring to the 10mm lock nut / 3mm hex fastener combo on the rear of the AFC housing.

I use this truck for work in the morning so I kind of need to figure out what happened ASAP.

As I’m dead in the water.

If anyone knows how to fix this I would appreciate advise.

Doesn’t even have to be good advise
