Compressor running

[f1racer328]

The front and central valve blocks were serviced with new o rings. There was quite a lot of desiccant dust build up. Still need to do the rear. My gallery pressure is building into the 170’s psi range. What should it be? It’s probably the compressor. Who knows has a good source on the oem hitachi?

You could probably replace it with an AMK and flash the new firmware with your GAP tool.

I would do this but there is a little work to do the conversion, a few existing pipes have to be modified I believe!

Ok finally got around to getting parts ordered up. Went with a new rear valve block from lucky8 and new Arnott rear strut assemblies from FCP. Pretty sure the passenger side rear bag was leaking along with the rear valve block internally as the truck was snagging on the passenger side and eventually the rear would hit the bump stops. That is with the EAS fuse pulled. Front would never move. Thanks all for the comments. Update when the wrenching is done.

Replacement of the rear valve block did the trick! Back in business.

Looks like it was leaking at the voss connection on the VB that was feeding the passenger side air bag.

The new valve block was an easy install with the brass fitting stripped from the line. The air lines just push into the new fittings on the new valve block.
