Hey thanks for your note. OER is a parts manufacturer of resto parts.

I took the tank out of the truck added a gallon of rust cleaner and marbles rotated it for several hours over several days, drained it an repeated the process. Then thoroughly treated it with POR Metal prep, followed by POR tank sealant. There are no obstructions.
I measured the resistance of the sending unit with an ohm meter and called the support line at OER, who never responded. I don’t believe the float is damaged or think it is filling with fuel, however that is worth checking out. Thx
While I have the sending unit out of the tank, I will retest the resistance of the sending unit. I’ll look at the potential of binding.
Thanks again for your thoughts
