Or even the rubber hose that connects at the fuel pump....
When I first was diagnosing a no start on my truck
I out starter fluid to start it but it had the same issues as you...
Then I took off the fuel filter to see if the pump was priming/pumping fuel I noticed no fuel delivery....
Then when I finally got around to dropping the tank and taking out the sending unit...
The rubber hose that helps transfer the fuel delivery was torn apart....
