Go to NAPA. They matched mine to one of their brand. I just picked one up yesterday. Pricey at $65. My Racor number is different than yours, but they will be able to cross reference it. 

I just had to replace my air dryer for a leak a few weeks ago. However, I could hear mine. While at it, I fixed another leak at a fitting.

I had time to crawl back under the RV today and get a better look at things. This is, in fact, the air dryer. I have an appointment Monday to have it replaced. I was absolutely wrong thinking this is something else. Chalk it up to a rookie error. Thanks to everyone for the input. Ivan, thanks for th picture and your insistence about what it is.

I don't think so. I am ASSUMING (DANGEROUS) that Monaco used a Wabco Air Dryer assembly on most of their motor homes.  That is usually located in the engine compartment and has a large filter (think oil filter design). The unit in the picture has no filter, or one that I can see and it would not be logical to put an air dryer behind the tag axle. BEST ADVICE...  Use an inspection camera and your phone... or drain the air tanks and take it off.  

Otherwise, carry it to an OTR truck repair shop that can do DOT brake inspections.  They will quickly tell you what it is and will replace it. 

As an aside, my Wabco started to leak a few years ago.  I sprayed most of the major components with a soapy water and found that the Wabco was leaking on the front and back. The kits for both sides totaled over $200 plus the labor from my shop.  I just bought a new one, which came with a new filter and had them replace it.  Kits for air devices can be found....but the cost of disassembly and rebuild, if you don't have the skill set...or don't want to, typically are MORE than a new component...

Let us know what it is after you

Let us know what it is after you identify it.

The air dryer is separate and is located a couple feet behind this part.

I have a 2008 Monaco Dynasty that is 45 feet with an ISM500. Not sure whether that matters. I am getting quite an air leak from the device shown in the pictures. Can anyone educate me on what this is and whether it is repairable or should be replaced? If it needs replaced, where do I go to get it and what is it called? I can’t easily see any writing on it, because it is quite a way above me. It is located behind the tag axle to the driver side of the engine and slightly in front of the engine. You can see the bubbles.

In your notification, it says to call Lazydays to reserve a spot. I did but the lady said could not register me because of “new system” being installed.  I called back the following week and she took down my info. She said they were not taking deposits and that I was registered. I never received any confirmation from Lazydays or paid a deposit as instructed in your email.  I also need to rsvp with you Guys. I definitely want to attend. Thanks. Sonny And Sandy Hale.😎🤭

I had the same experience with LazyDays RV Park. I will call in a few weeks or so to verify once again.

Hello Scotty. Doug and Nicki Craig will be there. We just made our reservation. Please let me know if there is anything else required at this point.
