Hi, my name is ***** ***** you for asking your question, I will try and help you out.

Most likely you have a leak on suction side of fuel system, this can be a hose, fitting, or more likely fuel/water separator.

fuel/water separators can crack over time it's a common issue.

I would bypass truck fuel system by running engine fuel system out of a clean bucket of fuel (5 gallon works well) take fuel line off fuel pump on back of air compressor (big line) run a hose from that fitting into bucket of fuel, prime system and get running.

If runs then bypass one item at a time before that point back to tanks to find what is leaking.

Any issues let me know I'm happy to assist.
