Compressor thingy-mahoozie

[Jimbabwe]

Check this out. Regarding my asking about my compressor fuses blowing and ground issues etc, a few weeks ago: Today I was taking the truck out to hit a couple of shows, when I first started the truck only one compressor came on. I looked and the fuse had blown on the other one. I had no issues the last few times I was out. I heard air coming out of the filter on the compressor head. I had heard this a few times before. I unscrewed the filter and put my finger there and a good amount of pressure was blowing against my finger while the other compressor ran. Shut the truck off, put in a new fuse and the air no longer leaked with both compressors now running. I installed check valves on both compressors a couple of months ago after getting the suspension done because it was airing out overnight with the noticeable leak from the tank through compressors. My questions are: How the hell is air coming out through the compressor when I installed check valves? Is there something in the compressor head that can be screwy and replaced? Could this have somehow been the thing that blows the fuses? Are there better check valves than these that I got from Ridetech, which obviously don't even work?

Gratuitous picture included.
