Found a 7/8 Craftsman socket inside the pump of a fire truck after it failed the pump test once, had come thru the water system and blew thru the intake screen. gave the socket to the chief and told him he could get a new one from Sears to help offset the 10K repair bill for the pump
Do a small test first, I tried this last spring on a trailer I built, the bed liner lifted the oil base paint up and bubbled all over, I had one big mess!
