this weekend my boat started having fuel issues. at the beginning of the season i replaced the fuel pump gaskets and everything fuel wise worked fine. but this weekend out on the water i couldn't get the motor to start, we had to use the trolling motor to get back to the dock. once i got home i removed the fuel liner going to the fuel pump, fuel came out fine through it. i then removed the out fuel line to the carburetor. i could pump and get fuel to go out towards the carburetor. i left the line off and attempted to crank the motor, no fuel was going through the pump. i took the fuel pump apart to check the rubber gasket. it was not damaged. everything looked normal. can i use a 12 volt fuel pump that is designed for collaborators. 1.5 psi to 4 psi. i took a separate fuel tank and placed it higher that the motor and siphoned it to the carburetor line and the motor ran. the fuel bulb was hard the whole time.
