Greetings, 2500 panel, 305E, SM420.

Real strange situation. Went to start it, nothing, would crank, no gas in clear fuel filter. I have had too many fuel pumps go bad due to ethanol gas so I changed the fuel pump.

Still nothing. I checked the fuel line under the truck and I noticed an rubber elbow about 5 feet from the tank. It was original and dry rotted and slow drip of gas.

Ok , I thought I found the problem. Installed a new rubber hose, still nothing.

Put another new fuel pump on with another fuel filter, still nothing .

Checked the gas tank for gas , its completely full.

Removed one end of the fuel hose where it connects to the inlet of the pump. I blew compressed air into the hose and a friend witnessed air and bubbles coming from tank fill spout .

Still nothing, cranks 15 seconds at a time, no fuel enters the completely new clear filter.

I am baffled.
