The fuel solenoid worked fine after installing a ground wire. Did find that the system drained back after sitting for almost two years. Now for the next question. This particular 2255 is a 4-wd with the finger/ball units in the front for steering instead of the universal joint shafts that Maibach makes. Used these in another 4-wd drive and they worked great. However I purchased this unit used and without a manual. I see there are grease zerks to add grease in the wheel hubs where the finger/ball units are. How much grease should be added and how often? I suspect the lack of grease was the reason the other ones broke so I don't want to repeat that. Since it sat for two years, should I add a very good high grade grease and put in 1/2 a tube in each wheel? I don't have a clue on these.
