Justy Like New
The regulator portion of this assembly is known for failure. I unscrewed the regulator from the 'T' pipe assembly, used it to replace my defective part, and everything worked just like new. Easy fix.

Look up the repair on the internet and there are several videos concerning the removal of the two bottom screws on the compressor plastic cover. Once you get past that with the help of the videos the repair is very basic. The removal of the two bottom screws is not difficult, they're just difficult to see.

The pressure regular failed.the repair was not difficult. Remove the existing parts that are on the failed regulator. The one thing you need to do is hold the housing it threads into. The factory uses a epoxy sealer on the threads. Use Teflon tape on the replacement regular so it will seal and to get it in the correct position. Install all of the parts you removed from the old one.

30-60 minutes
Tools Used
Screwdriver, Adjustable Wrench, small pipe wrench & 7/16 open end wrench
Parts Used
1.Unplug electric supply to compressor and drain air from tank.
2.Removed all Phillips head screws that support plastic cover above tank area & gauge face cover screws. (one side of the plastic is all that is required to remove on this type compressor)..
3. Gently pry apart & remove plastic cover not to damage gauges or plastic... Recommend starting at the handle area.
4.Removed quick connect for air supply while using a back up pipe wrench.
5.Remove pressure regulator gauge with a 7/16' open end wrench. Proceed cautiously not to damage gauge.
6. Remove defective pressure regulator & nipple with a adjustable wrench while using a back up pipe wrench on the positive compressor side of the pump. This is very soft metal so be smart and don't force anything to move.
7. Clean area around compressor side of nipple and make sure that no debris falls inside of open fittings.
8.Use threaded pipe tape to on new replacement fitting per normal pipe fitting specs.
9. Gently reapply the pipe nipple into the compressor positive side were the old part was removed from.
10.Possition fitting to make sure that it is not over tightened and is inline with how the replace part was positioned prior to removing it... This has to be correctly installed to make sure that all of the plastic and gauges are in place to allow the plastic covers to fit correctly.
11.Reapply quick connection fitting and make sure to use the threaded pipe tape on this fitting too.
12. Leak test the fittings that replace by plugging in the cord to electric and allowing the compressor to pressure up to 20 psi and turning it off .. Unplug electric supply cord from the compressor and use test solution or some dish washing liquid... Ten to 15 minutes should be along enough dwell time
13. After the leak test is successful release the air pressure stored in the tank and start the reassembly of the plastic cover...
14. Plug the compressor into the electric source, turn it on and monitor the pressure as it build up in ten PSI increments to make sure that everything is operating correctly before leaving it unattended...
Good luck with your replacement project! This replacement may not be 100% per the book but it worked for me.... The right tools for the job do make the difference...

Insert long flat screw driver on one side of the plastic cover and a 1/4 socket on the opposite side. Remove cover and use an adjustable wrench to remove the pressure gauge, once that's done, remove the whole pressure reducer. Make sure to put plenty of Teflon tape ( yellow) type to Insure tight seal and install everything back slowly and don't get frustrated, that just makes time seem longer.

Removed the 8 screws that hold the two halves of the plastic cover in place, the 2 long bolts that act as the attachment to the lower part of the cover, that bear the weight of the compressor, , take a long flat blade screwdriver and place in the slot in the nut on one side, and turn counter clock wise to remove it off the bolt, and at this time also remove the male hose connection from the reducer that is on the compressor, so you can remove the cover... the hard part is installing the new reducer, the round adjuster knob hits the bracket that is welded to the tank to hold the reducer and gauges, this should have been designed about 1/2 inch shorter, so the knob did not hit, , but it is a project that anyone with a little mechanical ability can handle with a just a few ''naughty'' words spoken
