I wonder (tongue in cheek) if ford fuel pumps are programmed to die around new years... mine apparently did the same thing. I'll run the checks to make sure but in the end I'll need to remove 50 gallons of fuel before I can drop the tank. This is not gonna be a fun job...
Banging on the tank did nothing.
BTW, does someone have a picture/page from the manual for the fuse and relay positions for the '99 chassis? perhaps '96 through '03 will do as well. Unlike GM, ford doesn't put a map on the fuse/relay cover of the sizes/purposes.
But the good news is the Onan genny started up after a couple tries, and ran like a champ with a load!
