Thanks Otto,
I'm pretty sure, at least part of the problem is/was a vapor lock.
When the truck was hot, there was no fuel in the line to the carb as well as an inline filter in the area.
And even with prolonged cranking, the gas would not get to the carb.
The elec fuel pump has seemed to correct this but still problems starting.
Thats why I am wondering if there is some additional problem perhaps electrical.
