just started up this engine for the first time this year. squeezed primer bulb and noticed fuel leaking out of the rear plastic pump housing of the VRO pump. Engine started fine and is idling fine. am concerned that once on the water the pump will suck air and stall. This occurred last year. Should I replace this VRO unit. The tech maual said this is a sealed unit and must be replaced as a whole unit. Where can I buy this unit and what is the approximate cost. Or should I get a non VRO pump and run this engine on a<br /> 50/1 ratio. Thanks for any help.<br />
