SOURCE: Air compressor won't build pressure

If this unit has what appears to be a pipe with fins on it , you may have a ruptured inter-cooler which will be leaking where you stated.

Probably the check valve has failed. It apparently is where the pipe goes into the tank from the compressor.

Remove the air filter and see if the inlet is sucking air if so the unit is pumping,if not the valves could be bad or the piston is broken.

SOURCE: Craftsman Air Comp. 6 hp oil-less, 33 gal horz. tank - sounds really loud

Sources of noise from craftsman oil free compressors (could be Made by Campbell Hausfeld or Porter Cable) include loose fan, failing bearing/s on the piston rod and housing, failing seal ring on piston, air filter intake and loose motor mounts. With the housing cover off, check the fan blade for cracks or loose screw. Turn motor by hand till the piston is at top of stroke. Examine the cylinder for scratches close to top. If scratched, air is leaking past vinyl ring making noise and causing longer fill time. If everything looks ok, suspect noise coming from bearings. Hard to tell if bearings are failing by looking at them. I have seen many failures of the piston bearing on the crank (fairly easy to change, I use alternator bearing from auto parts ) , however, the bearing in the housing just behind the crank bearing is much harder to replacable. Good luck with your fix-it project.

What ampage does your compressor draw ? If it is more than 10 amps you have blown a fuse . DO NOT PLUG COMPRESSORS INTO CIGARETTE LIGHTER SOCKETS ! RATHER CONNECT UP DIRECTLY TO YOUR VEHICLE'S BATTERY.

It is possible that the compressor psi as it is running drops below the tire psi creating a standoff. You must maintain air compressor psi over 110 to fill a tire to 110psi. Add air to your tire but stop when the compressor motor starts to run. When the motor stops then continue to add air until the compressor motor starts and again stop airing up the tire. Repeat as needed.

The compressor runs (rather noisy) but the pressure increases very slowly and not very high

Please do not take offense to anything I say but your compressor because it has nothing to do with you. It's a personal grudge against that particular air compressor and the Air Compressor **** that designed and built it. It is a piece of junk, and that's the nicest thing I can say about it.. The model you have was built for one thing and one thing only. It was to get an air compressor into the hands of customers that never really needed an air compressor for anything more then inflating a tire or a basketball. My friend's mother bought him one because, as she put it "it was cute". In all seriousness it is a throw away air compressor. I have seen several go bad with less then 30 hours time on the pump and motor. If it is bad and from your description it sounds like it, there is nothing you can do about it. Impossible to get parts for unless they come from another one of the same type. I'm sorry that I can't be more helpful. What I can say is you are better off to replace it. There are plenty of similarly sized and priced compressors that are far superior to the 3gal. 11/2 hp craftsman. The Senco PC1010 is a great compressor for it's size and specs. Good luck

Motor run for ever but tank does not fill up with air.

Sounds like you broke a valve. You could take apart the head assembly and check the reed valves but I would check to see if parts are available before you do this. Craftsman compressors are not the easiest compressors to find parts for.
