BREWSKI and any other interested parties,

The rebuild kits finally came (the diaphragm kit was separate from the valve kit) and I was able to get the truck running. I believe the barrel shaped valve behind one of the diaphragms in the AISAN regulator was the culprit as the rubber seal was starting to crack off. However, I did also push isopropyl alcohol through the idle trim injector by filling up the hose with alcohol and applying 12VDC to the terminals while blowing through the hose with my mouth. It looked rather dirty on the tip, and a bunch of brown colored liquid came out of the injector a few times I flushed it 5 or 6 times with isopropyl. I did soak the injector in an ultrasonic cleaner twice for a half hour, followed by an isopropyl flush. I hear many people on here say that you cannot clean these injectors, that you need to buy a new one. Seemed pretty simple to me, but I have no idea what the thing looked like on the inside. 9200 hours on this truck. I think it is very likely that it was just the valve behind the diaphragm in the fuel regulator that was causing the "no fuel" issue, and that the idle trim injector was just fine, but I have no way of knowing because I rebuilt the regulator and cleaned all of the solenoids at the same time. I hope this information helps someone else, and thank you for your help BREWSKI for helping me identify all of these fuel system parts, your assistance was integral. Now I need to find a local forklift service shop that is local that will not try and rob me, but that's for another thread. Best regards, Monte
