Me too bud me too.I try not to let mine get below 1/4 to avoid this at all cost.
Use the discharge air pressure from a shop vac on the fuel filler neck packed with rags to build up pressure on the fuel system, open the bleeder screw on the FF housing and prime until fuel comes out. Close bleeder and crank.I ran out of fuel and i put 5 gallons of diesel into the tank and primed the fuel filter valve until all the bubbles came out and just straight diesel was coming out. Any other suggestions or short cuts?
