Sound like good old Vapor Lock to me. Run it without the Air Silencer and c what happens. These big black cans help bring on VL.

SUPER-GLUE screw to screwdriver

CHRYSLER invented the torque wrench in the late 20s so this is would be the reason u cant find any spec for ur T6. Suggest u assume ur working with a Grade 2 Bolt/Stud and torque to the recommend torque per size.

Know what AIRTEX model u have
E8902
E8011

I also have a 1939 12, and have had no issues with the small airtex pumping through. Usually a flow regulator is not needed for the 12 models as I understand they have heavier duty needle and seats. As suggested check all screens and lines.

Just installed and AIRTEX E8902 (2.5-4.5 PSI) inline elect pump for priming in a '39 - '12'.
It will not push fuel through the factory diaphragm pump.
Anyone else ran into this?
Wondering if i upgrade to an E8011 (5-8 PSI) it would push through
BUT then would the press. at the carb. override the Needle&Seat.

Factory pump reads at 3.5 PSI at starter motor RPM with good flow. Fills the bowl from empty to the 9/16 within 15-20 seconds

Horn But, Light Lever, Throttle Lever
all an assy to a shaft/rod that goes thru the str column. U have to break the shaft loose from all at lower end and pull assy out/up then go from there. NOT a 10 min job.
