Maybe contact Onan to see if there is a kit that can adapt the FI gen, to the original MH wiring harness for the fuel pump. Everything for the FI should be on the new generator, so, just getting the wiring harness conversion would make this a snap to install. The AC side would be the same. Let us know how it works out. Could you inform us what the FI generator costs?
