77 440 Motor Home

Got it fired today. Steps I took:
1. checked for two fuel tanks, and it only has one.
2. Pulled the fuel filter on the rail, confirmed no fuel there.
3. Determined the mechanical pump was toast.
4. Found a electric fuel pump after the mechanical pump plumbed in the fuel line. Thought this was another filter at first. I traced the wires and found the positive was disconnected. Hooked it into key on and it fires right up. :) My thought is someone added this at one point.

Motor sounds strong, doesn't smoke. It is the HD 440 with the crazy water pump. The motor home needs some love but doesn't leak. Gonna put it for $1000 and see what happens.

Thanks for everyone's guidance.
