Found the source of fuel leak, the stepper is dripping fuel. It seems to be leaking from to top flange (held down by two torx screws).

Before I removed it... can I with the IP in the truck? Or should I just pull the pump, and install a reman. Truck has 96k on it, may already have a reman pump installed.

Stepper motor is an external and can't leak fuel.
The fuel leak must be coming from either the top cover(rubber seal) or either of the hex head bolts(check for being loose) just above and to the front of the stepper.
Top bolt is a plug, the other one holds the internal transfer pump in place and doubles as fuel path (kind of like a banjo bolt)there's 0 rings on it.O rings can be had in any Auto or hydr supply store
Can be got at with IP in place.
