Never really considered the tank slowing the process.  Hmm.

After having my setup in place for awhile, Iím realized the tank wasnít really doing anything. When I aired up, I was essentially filling straight from the compressor, because the tank would empty almost immediately.

With the Toyota, Iím going to forego the engine mounted setup, and run a tankless 12v compressor.

I completed my OBA recently using my Sanden A/C compressor. I got http://a.co/6QAYJtN from amazon. It's an open air chuck that clips on the tire. It always flows air when I have the compressor turned on. It really turned out pretty good.

That looks interesting. Now I'll have to go look at my hose, to see if I can put that on. It looks better than my HF chuck.

What I really need is a locking air chuck that is at 90į. So I can also use it on my motorcycle, that has a very minimal space between the stem and the wheel. All I have right now, that works is an old style chuck. Like the one in this picture on the very left. It probably doesn't exist.

Thanks Doug! Now I'll have figure out if I can fit it on my Inflator Gauge Hose.

Wonder if the hose on that inflator has standard threads on it?  I use a similar but without the digital gauge, I'd like to add a longer hose so I don't have to kneel down to use it (hurts my way too old for how young I am knees).

It looks like it does. My problem with the digital gauge is, well batteries. I'm not sure I would want to worry about them. I'm fine with the analog gauge.

Well today I went out on a hunt for a new hose for my inflator gauge. The hose has a pressed on chuck. I was looking for male 1/4" NPT threads on both sides. After going to 5 different stores, I failed. But someone recommended Rocklin Hydraulics. Of course they're closed today, so I'll have check it out tomorrow. I'm also looking for a longer hose. Because my (much older) knees don't like bending over either. I'll let you know what I find.

Oh, and also I went out to look at my old style chuck. And was surprised to find that i actually do have one of these:






I guess I have two different types.

Yeah, I may get that small tank you listed too since it has a switch etc. or may cannibalize the stuff I already have.

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?

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.

Hey Tim. My hose is longer than yours.

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.

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.
