While you are on the fuel tank give the sock (fine wire, plastic in some, mesh) that is on the pickup tube some attention. Leave the gas cap off and go to your fuel line upstream from the tank pickup and blow(blast) compressed air, at least 150 lbs back through the fuel line. If the sock is varnished up or clogged it will usually dislodge whatever is there or blow the sock off. That just eliminates a restriction in the fuel system. Be sure to not have your fuel pump in line or the cap on the tank when applying the air pressure. Another way to give the pick up attention is by removing the tank and remove the fuel line/sender access and remove the pickup screen.
