    There is a strainer in the fuel tank that may be plugged. Cleaning it requires draining the tank and removing the fuel line from the bottom of the tank. Then remove the strainer. The electric lift pump may not be working.

    Thanks for the infor, Just wondering, (to save draining the Tank, can one plow air back on the Fuel line)?

    I took the sentiment bowl off and cleaned it , then used the pump to fill it back up and that worked, but can not get the pump to push fuel any further.

    Loosen the inlet line at the inj pump..then run the electric pump.. It’ll push the air right out.

    Is there a screen in the sediment bowl ? If the lift pump is an Case OEM, it has a screen in it. I suspect you aren't getting an un-restricted flow of fuel from the tank. Blowing air back into the fuel tank serves no useful purpose. The crap is still in the tank and will come back to cause problems again.
