When we chatted the other day, you mentioned that you had previously had an external high pressure fuel pump, is that the one you still are running?
I was thinking, you could probably replace the complete in-tank sending unit with a carbureted version
My thought with that is to eliminate that non-working fuel pump assy, but keep the fuel float. I bet you can even buy one of those brand new really cheap.
The other thing I don't remember if I asked, was if the external pump is mounted at the back of the truck, they are best placed at the back and "pushing" the fuel, not at the front "pulling" the fuel.
