Fuel primer ball going limp Ocean Runner 225?

[cobbcfi]

When were off plane or down to idle the fuel ball is drying up so someone has to sit there and pump it till it's full again and then it only lasts for about 2 min before drying up and stalling the engine. When were on plane and or up to WOT it runs fine.

We pulled the fuel ball out and checked it with a pressure tester and it held vacuum for 10 minutes, so that's not it. Replaced the fuel water separator, that didn't fix it. I have changed nothing since last year and it was fine all year last year but since the first start this year it has become a real pain in the arse. Especially when riding alone.

Any thoughts??

The primer bulb is not supposed to stay hard after the motor starts, but it shouldn't get sucked in either. What you describe can be a number of things.

Your immediate problem is a fuel delivery problem, which can have a number of causes, such as:
. air leak on pump suction side (bad clamp, cracked hose, cracked tank pickup tube, etc., etc.)
. malfunctioning anti-siphon valve
. plugged tank vent
. trash blocking tank pickup screen
. plugged fuel filter
. collapsed fuel line
. check fuel pump output by taking off outlet hose and cranking engine over (make sure it can't start). You should see long, strong pulses of fuel. If not, pump is bad.

I was the low fuel pressure alarm vacuum switch on the port side of the block. The diaphram ruptured allow fuel to stream out of the weep hole. Removed that part, all is well..
