Sorry guys, been a little busy. New update...dropped tank, pulled intank pump, installed mech pump & bypassed regulator. Truck cranked on second spin, NO fuel out of carb vents, all adjustments now in spec's.
My take is the CONSTANT pressure from the intank pump is too much for the carb to handle, even with the regulator set @ 2.5 psi. Not quite sure how those guys who say that they use the intank pump & regulator are getting it to work. I tried everything.
truck runs great now with mech pump pushing 5 psi.
ssmonty & PatM,
Thanks so much for all your input. I've learned a bunch reading these forums over time so I decided to join. Hope to 'talk' with you all soon.
