I have an older Gen. w/ the ford engine and a newer Gen. w/ the fuel injected Nissan. A coulpe of things I would suggest that I did to mine. On both machines I got rid of the electric soloneid and replaced it w/ vacuum driven piston which I got from Powerclean. This solved all the problems I had been having w/ the diverter. On the fuel injected Nissan, after having to replace the ECU (computer for the FI). I think the reason it failed was they had it mounted right above the exhaust manifold where it was getting very hot. Not good for an electronic component. I moved it outside the whole machice compartment where I made a bracket which bolts to the side of the frame and sticks up a few inches above the cover. To do this I had to extend the wiring harness (about 30 wires) That was a pain in the ass but I well worth it. The ECU cost about 800+. If anyone has one like this I would suggest doing this.
