The best way to tackle intermittent problems is to travel with test eq and tools. If thats not poassible or time is of the essence then you start with the parts cannon but you have to use top quality parts or you may be inserting new confusing issues. The trick is an intelligent choice based on symptoms, history and scan data, not confirmation bias. It's not all engine computers and grounds. lol.

Good luck

Well I guess my hunch was true. After debating to drive the truck or not. I did take it out around town. Made a stop at the post-office then another at the local mobile phone store to pay bill, and finally just when I was feeling positive about the pump's working state. I made a final stop at the gas station. After pumping up the fuel pump just died. It died running parked. Could not get it to start up again no matter how hard I beat the gas tank. Had to get a towed back home. I guess im buying a pump, Also was considering swapping out the fuel tank asm with a plastic one. Anyone every do anything like this??

 

Fuel pumps seem to die when the tank is full. I do not know why this is....but sure seems to always happen.
Mundo: If the metal tank is good, why replace with a plastic one?
Anyways, hopefully the fuel pump can be used to empty the tank out, makes dropping the tank a lot more manageable.
Oh and be careful removing the filler hose off the tank as replacements (if even available anymore) are not exactly the same. Do all you can to save that filler hose.

 

That is a clever idea to use the old pump to empty the tank. I've borrowed several gas cans from friends to be sure I have enough to accept the gas I need to remove.

I was able to find a filler hose that attaches to the tank but not the vent hose. However, pictures of the vent hose at the GM parts stores showed markings that showed it was 3/4" ID.

Off the top of my head, the filler hose for mine is 2" ID.
Edit: It is 2" ID.
