Does your truck have a fuel pump safety shut off?

Well, I would replace the fuel filter first, cuz their cheap and easy, and then you'll know it's clean. If that has no effect, I'd grab a length of rubber fuel line, like 6-10 feet long, and connect it to the fuel pump inlet instead of the rubber hose that connects steel line to the pump inlet. And try starting it out of a gas can with known good gas. May take a bit of cranking to get fuel all the way up to the carb.

If it runs fine out of the can, then you know where to start looking:

-cracked rubber fuel line on pump inlet letting in air, or
-leaky or plugged steel line from back to front
-rubber line from tank to steel line
-tank pickup line cracked/broken either on outside of tank, or inside tank
-tank pickup sock filter plugged
-tank smashed, etc

Really, if it runs fine out of a gas can, I'd give it a real close visual first from front to back, may find something broken/bent closed/disconnected, etc. considering what happened.

If not, you could hook up the pump again to the steel line, and move the temporary gas can setup to the back end of the steel tubing near the gas tank, and try running it again. Need to run long enough to use up all gas in carb bowl (so ya don't think it's fine, when it's really not, just running on what's left in the bowl, if that makes sense).

It doesn't take much of an air leak under fuel pump vacuum to pull in air instead of fuel.
