Mechanical fuel pump, top cover on IP, CUCV is 12 volt

Temp sensor from the humvee on the front side of the left head, cold start advance sensor from the rear side of the right head. Pull the vacuum pump and install the oil pump drive from the HMMWV engine. The oil pan can stay. It should not interfere with the HMMWV exhaust and there is lots of room everywhere else around it. When the Military went to the Turbo engines in the Humvees, they used a "normal" style of oil pan instead of that large sump type, so unless you are trying to keep it looking original, just keep the pan on the engine that is already there.

I pulled the engine today,Now I have to switch parts.Does anybody know if I have to swap the flywheel ? They look the same..

Flywheel is the same, but they do crack, so I'd put a new one, or take a good look at it and look for hairline cracks.
