Might be a fuel deivery problem. Might not. This issue happened for the first time after someone worked on the fuel pump? You've driven it 1,000 miles, so presumably you've run the tank low a few times? When you put the 3 gallons in did it seem like there was a vacuum in the tank when you removed the cap? You might want work towrads ensuring all the lines are clear, filter is clean and the tank is venting properly.
Leaking at the fuel pump where? At a fitting, or the diaphragm screws, or at the the weep hole? The latter means the pump is defective and needs replaced. Check crankcase oil for evidence of gas contamination, i.e overfull on the dipstick, take a whiff.

First ever fuel issue was after just the leak issue that was gone through
Have run the tank down many many times. Altitude drives between 4300’ - 6900’
I did not hear any vacuum on the gas tank
Will definitely check on the lines are clear, filter is clean, tank is venting

I don’t remember the Resto mechanic said went he went over a short list of it all while there
Will definitely get deeper and thanks for that info
Love your truck by the way. Anyway, assuming good fuel delivery.... Hot weather and a bit of elevation in Sedona and starts back up after a rest. Vapor lock?

Thank you very much on the truck
fuel delivery is so strong till this last issue and I go to Jerome at 5000’ just under an hour. Flagstaff is 7000 at the same just under an hours
this trucks gets driven almost everyday and is just slowed being driven since it came over 100 degrees here
would agree that vapor lock is could the leader possibly
If you suspect vapor lock get a handful of cloths pins and clamp them on your metal line going from the fuel pump to the carb. See if the cloths pins dissipate enough heat to relieve the issue. If so changing the steel line to a rubber line may be a permanent solution.

If it continues to be a problem and if none of above helps have a flow through switched auxiliary electric fuel pump installed at the tank.
If nothing else it will be a backup if the mechanical pump should fail.

Thanks for the update and another picture. But remember some thought it might have been vapor Lock..... But wherever you are now, it's not 108° like it was when you first reported this problem. Where are you located anyhow?
Having grown up with flatheads I can tell you that vapor lock is a very real posibility. Along with overheating on mountain passes. It was pretty common back in the day.
