Specs: '46-48 59AB, all stock (other than dual exhaust).
Ford 94 carb rebuilt & double-checked for float level & needle stickiness. Under my ownership, the truck only ran once, when the PO loaded it onto my trailer. I didn't see exactly what he did as far making it run, but it climbed the trailer ramps well enough. Gas stunk to high heaven tho. Project slept.

13 years later and I am right on the edge of getting the truck rolling again. As I got it, the mechanical pump was bypassed (no line in or out) and an ancient Bendix 6V electric pump was doing fuel duty.

Recent re-start procedures had the Bendix running seemingly fine; pumping vigorously when the toggle was turned ON, then slowing & stopping when the system was pressurized. Ignition issue prevented a restart. Ignition issue was remedied (thanks Skip!), then Bendix was acting very sleepy and would not run at the same speed nor feed the carb.

Filled carb manually and started truck, ran smooth as silk until carb emptied. Did this twice.

Replaced Bendix with Airtex E8902 and it runs fine but floods carb out the vent tubes. Rechecked float & valve- OK. Airtex recommended a regulator.

Question : if I install a regulator to address flooding, can I theoretically run the electric pump ONLY and continue to bypass the mechanical pump?
