1997 225 oceanrunner

Have a 97 ocean runner. New tank and lines. Boat ran fine befoe and after tank installed. Now its running outta fuel. Primer bulb is not sucking down just loosing its prime. Can primer solenoid be a cause or fuel pump issue? Thanks

Have someone pump the fuel primer bulb constantly, acting as a manual fuel pump. If that cures the problem, you either have a fuel/air leak between the primer bulb and the fuel pump, a fuel pump failed internally, or a blown piston that operates the fuel pump.

Does your warning horn sound off momentarily when you turn the key to the ON position?

The fuel primer solenoid is not at fault... impossible to have the engine run out of fuel UNLESS it's leaking and spraying fuel all over the powerhead.

No leaks anywhere and has new lines from tank to pump. If someone pumps the ball as its running itll stay running. I pump the ball tight and itll fire right up and run for like 45sec then loose prime and ball is soft again.

Air is a lot thinner than fuel. Therefore air can leak into fuel line, w/o fuel leaking out. If the bulb is full, but soft, the air leak is between the bulb and the motor. If the bulb is empty, the air leak is between fuel tank and bulb.

Some of those motors have a main strainer under the airbox. They have an oring and gasket to keep them air tight. You might check those.

If someone pumps the ball as its running It'll stay running.

That indicates either a fuel leak between the fuel pump and the fuel supply... OR... a failed fuel pump. If a kit is available, I'd suggest you rebuild the fuel pump.
