The air in the cracked fuel lines tell the story..
Your sucking air.. which could mean a clogged tank outlet..
The reason it runs for a short time is, the supply pump is sucking the fuel from the filters..& by the time u get there to check it, gravity has filled them back up.??
Check every connection from the tank to the IP.. one might be sealed with a rubber grommet.. the grommets get torn but won’t leak fuel BUT WILL suck air..
I would start at the filter INLET.. take off the line and put in a 5 gallon bucket.. fuel should flow freely..
Let it run for a minute or two.. any blurps and u got floaters in the tank.
If ok, hook it back up and go to the other side of the filter..
Remove the line and check the flow..
