I was on my way early this morning to get the big 60 gallon 220v compressor from Atwoods for $499 and pass this little place not more than about 4 miles from my house that had a sign with tools for sale. I said what the heck, let me check him out. It was like a pawn shop inside but with mostly new stuff and a few used. He had a 2 30 gallon oilless type but I didn't want any more oilless, Then I saw this small twin tank PUMA brand 2HP and 7.4 CFM @90 PSI that looked good for $100. I decided I would just get that for now and plan was I could tie it into the 31 gallon tank off the Craftsman for extra storage as the compressor was as high or higher than my 30 gal Craftsman. I used it all day running the big 3/4" HF impact and it worked pretty good but does cycle a lot but pumps up in less than a minute. So when I finished work, I started taking the Craftsman apart. I took off the head and looked at the piston, all the valves and piston looked good, so I put it back together and plugged it in to run and it was really sucking air in thru the intake with lots of vacuum so I started looking at what else could be a problem. Maybe that little sending unit line to the shut off controller, so it took a wrench to it to see if it was tight and one end just turned round and round. Took that line off and the aluminum line had sheared off inside the compression nut. I finally got it off and the piece of tubing removed and jury rigged the compression fitting by drilling out the swage so I could get it back over the pipe as I didn't have anything to fit it. Well I got it back together and it seems to be holding and TADA, it pumped up to 130 and shut off just like normal. Now I have the little one and the big one, so now to see how I want to use them. I am going to get a new copper 1/4" OD tubing with new compression fitting to replace that aluminum line and it will be better than new.
