Yeah, I may get that small tank you listed too since it has a switch etc. or may cannibalize the stuff I already have.
That 1/2 gal one was cheaper on eBay:

I use one of these. I like it.

So the second link clicks on to the valve stem right, and the difference in "open" and "closed" is air flows freely "open" and it has to be seated on a valve stem if it's the "closed" type?

That's my understanding. It looks similar to a standard coupler but it is smaller and fits a valve stem perfectly. No leaks and tough as nails. Just need a barb to fit your hose.
I cut the original chuck off when I snagged and broke it. Here is the actual inflator I have (not digital).

Are you going to use a small tank to buffer the pressure?

I went to Rocklin Hydraulics today. They told me over the phone that they could hook me up. And Tim and I were texting about it. Well they couldn't do what they said they could over the phone. But Tim found this hose, which should be perfect.

I'll get it by March 9th.

Iím gonna take a look at it and see where I can fit the compressor and see about a tank location. Most likely use a smaller one than the 2 gallon I have now.

Why not build a tensioning pivot into the compressor mount?

Thought about that too.  The belt I'm using now has to be special ordered when I replace it apparently it's a stock size for a couple of older Porche's but nothing else really.  I'm just going the electric route and get back to the stock belt etc.

I have a NIB 480c. My son and New Jim expressed interest in it. Don't buy one yet. I found a rebuild kit for my 550c so don't need it.
This can be had for $94 Amazon Deals (3.5CFM claim)
https://www.amazon.com/dp/B00OLRCKQK/_encoding=UTF8?coliid=INDI789QXS1CK&colid=3Q6QSLQWNYSKN&psc=0

Sooooo, I put that compressor on my wish list before I got your other one.  I was looking at the list today and that $94 one in the Warehouse deals had dropped to $64!!!  Yup, I bought it too, so if I can figure out where to mount two compressors and I'll run duals.

Wow, that is a good price. Wonder how it compares to a Viair. Like someone mentioned, they're all made in China. You have almost as many compressors as I have LED's  :laughing: I bought another pair of those DOT legal pods, they went up $50 a day later.

OK, so question.....

I figured out where and how I'm going to mount the two compressors and get them into one feed line. 

The question is if I ran that single line into a manifold like this... https://tinyurl.com/yasjwjkn with a pop off valve, pressure switch and a coupler for the fill line, will it build enough pressure to shut off the compressors?  I'm assuming the answer would be yes, and if so there's not really a reason to run a tank. 

My concern is having a way for the compressors to cycle on and off, so if I'm going from one tire to another etc they're not just constantly running build however much pressure until a line ruptures or whatever.

I will try to install my tank bypass valve today and see how the pressure behaves without a tank. I guess worse case the relief valve might vent as the compressor is cycling down. I am going to reverse the hose coupler so at a minimum I will have the capacity of the hose as a tank. Hope I don't blow the hose!

Yeah, that's my worry.

I think it'll work.  I just don't wanna buy another tank if I don't really need one.

The results are in and they are not quite as expected:
The manifold alone is fine, I didn't need the hose as a buffer. The compressor stops pretty fast. 125 PSI with a 120 PSI switch.
I used a stopwatch and timed airing-up from 8 PSI to 20 PSI.

1st tire took 60 seconds starting with a full tank and open bypass valve. The tank dropped to 60 PSI.
2nd tire took 1:40 and the tank dropped an additional 10 PSI
3rd  tire also took 1:40 and the tank remained at 50 PSI; I would assume the 4th would take the same time.
4th tire I filled directly from the compressor with the bypass valve closed (no tank) and it took 2:10

Seems like a 2.5 gallon tank is better for some reason. Guess you can only push so much air through a valve core. IDK

Thatís very true. Itís why some people remove the core prior to filling. Also powertank offers a fast fill valve stem to fill big tires fast.

Glad I am in no hurry. $$$

I think I'll just get a longer fill hose so I can stand up while filling tires.  :thumbsup:

I was at powertank a few weeks ago. Owner showed me the monster valve system. Pretty trick. A bit fancy for me. I subscribe to the KISS principle.

Picked up 15 pound tank  for a screaming deal tho because it was on the blemish shelf.  Although, we couldnít find a mark on the thing.  Although it is bought air that runs out, should get over 50 tires aired up.  Tire takes about 20 seconds to air up.

I had a 10 lb tank, would air 5- 42 inch tires from 4psi to 26 psi.
Very quick, 22 dollars to fill in and exchange.
The problem with C02, besides cost is you really have now way of telling how much is in the tank.
