Forest, I also have a Gast compressor mounted in the same location. The only difference is mine has a capacitor which puts it really close to the gen. exhaust. I do not have a check valve nor a water separator. I like your set up. I have to drain my rear tank about every 10 days. I have a question as to why the check valve? Is it to keep air or water from draining back into the compressor? Also where did you buy the check valve? I know where you bought the water separator.
