What model air compressor is this? Does it have a built in pressure switch so it cuts on and off as you use it?
The compressor in the referenced photo is a Superflow MV-50 or Masterflow MF-1050 (same thing). It is a basic, no frills entry-level compressor that does not have a built in on-off pressure switch.
Thank you.
I think I've found one just like it at Northern Tool. (https://www.northerntool.com/shop/tools/product_200672539_200672539)
Do you happen to remember what thread size the exhaust port is on the compressor where you attached your quick connect?
Is it the same size as where you removed the original gauge?
You're asking the wrong guy. If you read my posts, you will find that I think those little red cheap Chinese compressors are junk and a waste of hard earned money. That's why I am using a Viair 400 series compressor instead (the topic of this "how-to" thread BTW).
But to answer your question, although there are some reports of Masterflow/Superflow changing the thread and pitch of the threaded holes in the head to 1/4" NPT, which is the standard size for 12v portable compressors in the U.S., to the best of my knowledge they are still using 1/4" or a metric BSP thread which is not compatible with NPT and requires a tap and die to make the conversion.

None.
"Only" 33% is plenty for the Viair 400, which is rated at 2.4 CFM at 0 psi and 1.86 CFM at 30 psi.
Viair defines the 33% duty cycle for the 400 series 12v compressors as 20 minutes run time at 100 psi at an ambient temperature of 72*F.
Viair claims fill rates for 35" tires of 0-30 psi in 5:20 and 15-30 psi in 2:45.
I can easily air up four 35" tires in less than 20 minutes.
I am airing up to 24-26 psi, not to 100 psi.

Ok, nice.
Is there plenty of room where you mounted it? Would it still fit there if it were 2" longer?
