An update on what's going on. I installed the control valve for the dump valve and that fixed a major leak. Found that both the fittings on the dump valve actuator were leaking a little, the lower one stopped with a little tightening but the upper one doesn't want to snug up, must be stripped. I am now going to have to replace it anyway because when I was pulling the actuator to replace the gate my hand slipped and snapped the fitting off. Found them on the net and they should be here this week. Had to buy 10 so if anyone needs one give me a shout. also found the drain valve for the wet tank and the tank near the 120v compressor leaking, replaced them, no leak. The only other leaks I have identified at the fittings for the lines going into the left rear drive axle brake (you can barely hear it with the Inficon) and the left rear HCV. The leak at the HCV is coming from underneath the valve not from the fittings so I guess that means a new valve is in my future. The rig is holding pressures much longer now but is still slow to reach operating levels. It took about 6 or 7 minutes to reach about 110 PSI from a starting point of 75 sitting at idle, never did reach its usual 120. Still haven't installed the new governor and dryer, maybe they will help. By the way, I give up, I have crawled all around under the beast and can't find more than 4 tanks. I have found the two brake tanks (drained them, one was dry and the other only had a few drops of water), the wet tank and the tank at the 120v compressor. Can't find the rectangular tanks I hear mentioned all the time or any others. The only thing close to looking like a rectangular tank is a large tube steel cross member just forward of the drive axle air bags, it has a plug on bottom but no drain vale and I don't see any lines going to it. I have also (after being admonished) searched the forum in every way I can think of to no avail. Can anyone give me a hint as to where the rest of these 10 or 11 tanks are?
