When it worked I loved it. Now about this much with a hammer. It sat in my empire of dirt too long, this was motor recovery so my buddy might be able to use it on his little Shoebox clone that twisted off the motor shaft.
It's a shame you did contact one of our members here colt 1900. He has all the parts at a very reasonable price to repair all GX CS pumps. I think you could still by the parts off him as it sits and have a working compressor cheaper then buying a new one from him. By the way everyone he warranties them and you can talk to him about problems so the right parts are coming your way.
