Re: [Cal_Boats] Yanmar Fuel Pump

Thanks! Darn. I'll order a new one -- won't be able to install it for two weeks. The manual didn't show any problems and, other than bleeding the system after installing, there don't seem to be any bumps. Anyone know of any, or is this replacement as clear as it sounds?

It appears to be leaking from the gasket that seals between the upper and lower halves of this pump. My SELOC Repair Manual only tells how to remove and install this pump and does not give instructions for re-building. Is this pump re-buildable and is there a kit that I can order or should I just order a new lift pump. Thanks in advance for your continued help in these engine matters!

Yanmar upgraded the fuel connections to and from the pump. They originally used metal tubing, but vibration caused air to enter the system. The new arrangement uses hose. I would check for upgrades or service bulletins with your Yanmar supplier. You may need the engine serial number.
