Onan 7.5 KV MDJE Transfer Pump

The transfer pump in my about 1978 7.5 KW MDJE gen set is seeping a little fuel. I understand that the pumps are no longer available, but I wondering if there is a rebuild kit available or perhaps someone who can make the gaskets and diaphragms.

Thanks,
Bob

Snug up the screws around diaphragm. If no joy, replace it with an electric pump. 5psi universal from auto parts store will do the job. Cut a blank of plate out of aluminum to seal off hole in block.

The electric pump will also make it easier to bleed the injector pump and when you change the secondary filter.

It looks like I'm getting an electric pump to replace my leaking pump. Does anyone have a brand name or part number to get me started?

Thanks,
Bob

I found this pump online. Could this possibly be enough pump. It's only $15.

I've had great luck using the Holley electric pumps. Very reliable.
