Bit of an update, I've ordered the $50 compressor solenoid valve part as per the code. Unfortunately the air issue is getting worse. If this thing sits for more than 2 hours the front end drops right down. I'm gonna wait and install this part but somehow I highly doubt that a $50 part is gonna fix all my air leak issues. If it does i'll be doing back flips.
Lets just say I've done my coil research and already have the kit in my check-out basket on Atlantic British. I know the air is far superior and I'm not opening a debate about that but I just want a reliable daily runner that can take my family camping occasionally. I already have a D2 bush buggy so the coil conversion for me seems like an easy choice.I didn't pay much for this truck and aside from the air issue it's been great.

 

The solenoid valve will fix the fault but you may still have a leaked at the strut. Have you confirmed that you have the AMK compressor? Remember that the drier fixes the same issue on the Hitachi compressor.
