  Howdy,,,I have a Dewalt D55146 portable roll around air compressor that am having issues locating repair parts for. 
 It is leaking air at the regulator and both Amazon and Ebay do not list the regulator by itself but do sell the regulator WITH the manifold for $200 +-
 This regulator started leaking last year and the only part available then was a "REPAIR KIT" which I installed,,but now that DANG thing is leaking again. You can order a manifold from amazon or ebay with the regulator but no gauges etc but also very pricey,,,,,

dont see the reg by itself.... you can get the ENTIRE package with gauges and reg for $200 as you said... this appears to be the CHEAP option.... unless you buy a generic regulator and some pipe fittings and screw everything together... Probably still have $90. in that..

 Hey Steve,,I was hoping to buy an OEM, shore enough Dewalt regulator as I already bought one of these "generic" rebuild kits for that regulator a year or so ago. The Factory (OEM)  Dewalt regulator was NOT available then either,,,,? The main item description heading on this one says OEM,,,then right below that,,it says Brand is GENERIC,,,,?? 
 The "Complete"one you also refer to at $200 is also "generic"
 Being some what,,,"Thrifty",, I am now considering looking for a popular brand name regulator with it's base fitting and make my own manifold  as there seems to be lots of traffic for the Dewalt replacements,,,prolly for good reason,,,errrr,,,bad performance,,,!!

I went to HF and purchased an inline regulator for my roll around unit (Campbell Hausfield). I reused the gauges and other fittings and didn’t have to spend much money.

 Hey Hubert,,Thanks for the comeback,,,,Yes,,that right there is what I figured to do to get a quality regulator. I'm  now thinking the Dewalt regulator is manufactored for that specific manifold and the china rebuild kits that are being offered are some less than optimum clearances as the leaking has been thru the regulator adjuster body itself as the adjustment changes is to "PULL" the knob to adjust,,then push down to set,,,kinda a rube goldburg sort of fu,,,! 
 I saw the one by Porter Cable  ($16)  that HF offers and it is a name brand product and I expect I will rebuild the whole manifold to my specs and reuse only the 2 gauges and the pressure relief valve and replace the 2 hose quick connects as they are also less than optimum. Thanks again.

If that part pictured is a manifold - then I would make up my own from pipe fittings .
Standard Sch 40 water pipe is rated at 125 PSI so if you set pressure switch to that or less it would be OK or go to next step and get Sch 80 pipe and fittings with a 220 PSI or greater .
  I would make a manifold with a couple ports and install quick disconnect fitting into it so regulator could be plugged into it when needed , not in use at all times .

 YEA,,!!!,I've always been of the opinion that great minds think the same way to resolve a puzzler, thanks to these folks that take the time to help others,Clap

 My plans are to use 3/8" S/80 CS pipe fittings to make up my manifold with two new quick connects as the factory ones are so Dang hard to force the hose end into the quick connector. Plan to also reuse the two pressure gauges and the relief valve as no issues there either,,
 Wish me luck,,,and Thanks again,,GuysClap
