Just a quick F/U for the evening. A clean tank replaced with new flexible gas lines. Presently draining the gas back into the truck. Electric fuel pump primed itself quickly. Turned it off. She fired up quickly and is running smoothly.
So like an airplane, I have redundancy for fuel pumps.
Dudnt really find the problem but it seems to be cured.
Want to thank this web site for its followers & positive input to my problem.
The other probably just needs to get a job & grow up!
