[QUOTE="Johnny, post: 439831, member: 13599"] like Shaugh said: disconnect the fuel hose on the "outgo" side of the fuel pump and connect a longer hose to it to flow into a clear plastic bottle. crank the motor over. this will give you an idea of fuel flow. also - if you are running SeaFoam in your gas, you may have an accumulation of water in the bottom of the gas tank. fuel delivery issues will drive you [i]nuts[/i] before you finally find the problem. oh - what brand of fuel hose and primer bulb did you purchase for replacement ??? how is the primer situated to the motor? it should hang in the vertical position to maintain proper fuel flow. (photos of your fuel tank and hose might help). did you change the "fuel filter" in the gas line or inside the fuel pump ? . [/QUOTE]
