need help with fuel system 200 johnson ocean pro

[brian miles]

ok here we go. have a 99 ocean pro that seems like a fuel starvation issue at any higher rpm the primer bulb will collapse starving the motor from fuel we can disconnect the fuel line get the bulb to release and run again for about 5 min then again. what we've done. we took out the pick up line inspected it and the tank, all good replaced all fuel lines and vent lines installed new primer bulb,fuel filter. all the vro system is disconnected and the oil side is plugged off, was this way when we bought the boat. we did do something with the fuel line awhile back can't remember completely but there was a t in the line (fuel line) it went to the block i think. we removed this and ran 1 line straight to the pump, my nephew seems to think this is when the problem started, i've disagreed, but maybe i'm wrong.oh i almost forgot we drilled holes in the bottom of the pickup line in case it was a clog at the bottom fuel would still be delivered. any help or guidance would be greatly appreciated.

you have a blockage between the fuel bulb and the fuel tank. is vent clear on the fuel tank? clogged pickup in the tank? antisiphon valve?

thats exactly what we thought,as i stated we removed the pick up line from the tank checked it out drilled holes around the bottom of the stem installed new hose from the tank to the motor no anti siphon valve except in the bulb. what do you think.

try running the pick up line to another gas can to cancel out tank. then cancel out filters. water separator. thinking primer.
