...The fuel injection system appears to be an Accel Gen 6 MPFI system, the same as I run. I was probably put together by Rance Baxter at rancefi.com . Do you have the cast iron or Edelbrock manifold. The Gen 6 system if everything works will just motor down the road. You don't need to play with it or change parameters or you will be parking it. The computer is the hard part to find and the rest is pretty much available ;off the shelf. I didn't bring my parts list when we left for Tucson, but I have found the injectors , fuel regulator. What color injectors do you have? When I get home I can get you all the information I have rounded up on the Accel DFI system. When you go to his site go to the GMC motorhome page and click on the 500 Cadillac 4 barrel style. The Gen 7 upgrade is the next step if you want to upgrade the electronics, the manifold and injectors are reusable.
