I don't know. But I'm going to give it a shot. I don't expect to sell them for 100 if they cost me 100 but it would be way more reasonable than 250. Will see if they are even willing to talk.
 
Attached is a pic of the bpst? elbow from the head. I guess I'll try and find someone with bsp thread gauges to be sure, but it's most likely that's what the thread is. Also shown are pics of the separated pump, the Anderson quick-disconnect cable I made up, how I store it in the Taco, and where I plug the cable in.

More pics. If anyone has come up with what that elbow thread size is, please let me know.

So you got rid of all tank, pressure switches, etc. and just used the compressor part....pretty cool mod! :beer:

Nice set up:cheers:

Any data on how much faster it is now?

I'm think'n a pop off valve is needed to be on the safe side
 
It may be an AN thread or a metric equivalent. It is obviously one of the parallel pipe thread styles. The bevel tells me it is designed for pressure as that seats against another bevel or o-ring.

Edit scratch that, you were looking for the horizontal one. I was thinking you were trying to figure out the complex one. Yeah, it looks like any of the tapered pipe threads. There BST, JIS, and NPT to choose from. JIS and BST are equivalent for the smallest few.

Bogo, I exhausted the npt and jis gauges, so it oughta be bspt. Do you think it's 1/4 bpst?
 
Look at the diameter in comparison to the figures given in the tables at the web pages I linked to in my last post.

Most likely. If you never intend to use the old fitting, get a NPT tap and tap the hole to fit more common NPT fittings?

X2, or modify the coupler to be free flowing/leak, or install the nipple on the head and coupler on the hose. With that setup you want everything free flowing, couplers, inflator adaptor, etc. If the pump is accidentally turned on with the output blocked, high pressure will quickly build, possibly bursting something, causing injury.
 
Adapt-all said that it is most likely 3/8 bpst based on my caliper msmnts. Plus, it was an almost fit to a 3/8 IP size at hardware store. I plan to order a 3/8 bpst male x 3/8 fnpt adapter and go from there. I'll let you know how I make out.

Thanks for the feedback, folks. I believe I will add a pop-off on a t fitting prior to the coupling. I had thought of a rocker switch at the pump, but then that wouldn't be as convenient as a set and forget pop-off.
 
So I may have buggered up my pressure switch/relay thing. Anyone know where I can get a nice replacement? I checked KMS tools and Princess Auto, but the largest pressure switch they have is rated at 40 amp. Not enough right?
 
You could have a pressure switch operate a heavy duty relay or contactor which then operates the air compressor.

That is likely an AC rating? The stock one is rated 15A 250V AC or 20A 125V AC. In DC mode, both sides of the switch are jumpered together, so what you are looking at should be plenty.

You're right Tools. Thanks. And even better news, I spent the better part of an hour last night fixing the damn thing. So now I don't even need to replace it :cheers:

I'll post some pics of it soon, divorced from the tank and all installed neat and tidy in my new rear cargo drawer system.
 
Question about oba... not really Puma related, but I figured this could be a good place to ask it. I'd like to have the tank pressure gauge in my console up front, next to my switch for the relay to send power to the puma in the back. Since it's only a gauge and doesn't really need flow, can I use a super thin air line? It'd be travelling all the way from the back of the Cruiser to the front, so standard sized air line would be a PITA.
 
Just get standard 1/4" OD compression fit air line like used for air-bags from Firestone. 3/16" and 1/8" OD lines often cost more and may not be stocked at any old Firestone suspension garage. Something about supply and demand. All the 1/4" OD parts are commonly available as that is what is used by all their consumer air-bag kits. BTW: Many other manufacturers make and use compatible fittings and hoses.:hillbilly:

Never bought from these guys, but they sell them. Only using them as an example to show which parts I mean:
General: Firestone Air Bags, Firestone Air Springs - TruckSpring.com
Fittings: Air Fittings, Air Hose Fittings, Hose Fittings - TruckSpring.com
Hose: Air Hose, Air Hoses, Air Line Tubing - TruckSpring.com
They actually have the 1/8" less than the 1/4" which it should be because it uses allot less materials.

BTW, I'd have at least one plug in your emergency kit for each size of port on your air tank to allow capping them off if the line gets cut.
 
I'll call your attention to Firestone Ride-Rite kit No. 2196. It is a 2" gauge, gauge mount, 18' air line, a couple Ts, and an Schreader air valve all in one kit. It is made as a cheap air-bag control kit that uses an outside pump, hence the Schreader valve, for air input. A PDF of what the kit has in it: http://c452191.r91.cf2.rackcdn.com/images/bbqz/image/rrin2196.pdf A quick search I saw the kit for $56.

BTW, also look at replacement parts, but be mindful the replacement gauges have threaded connects and need fittings to change them to the pressure fit hose ends. I got bit by that.

When I got parts for my air-bag install I got one of these kits to get the parts in it for other uses.;) I have an onboard air tank for the air bags, but no air compressor. Eventually I'll add onboard air compressor, but I have a MV-50 I can use to pressurize the tank.
