I figure I'll use the dial part and hook a momentary switch to it. Mount the compressor under the truck in the rear and have only one line ran to the cab along with a momentary on/off switch. Put a relay in line to handle the load.

Can't wait to see it installed! Sell me the bracket and leftover parts !

Let me get everything figured out and we will work on it.I just couldn't pass it up for that kind of money.
I figured it would be faster to!
Never know I may add set of bags up front later.

Well I brought the pump to work today and we hooked it up to a small vacuum pump we have and it worked for a while then quit.

I took it a part and cleaned everything real good and then lubed everything good before reassembly. Put the vacuum pump back on it and it worked like a charm. When you turn the vacuum on it will fill the air shocks up are in my case the air bags and then you shut the air valve off and it just sit's there until you turn it on again.

I'm looking forward to seeing the setup installed! I gather the vacuum pump drives a cylinder that intakes air, which is then diverted to the rear shocks through the controller?

I'd also like to see pics of the GM Superlift shock option that some 67-72 trucks were outfitted with. Anyone?

[Andy4639]

DeadheadNM,
Here is a picture of the pump and me explaining it best I can. You can take it a part and look at it. Nothing major except the rubber seal. You don't want it to rip. I took mine totally apart and cleaned it good.

Pete, I know you like collecting options but like the helper springs these were not offered "factory" on the K20, nor per the data book any leaf truck. Are there any GM air shocks long enough and rated for your truck that will fit? Probably have a hard time finding any new aftermarket shocks to fit your application as well.

However you could probably use the controller for some airbags if you needed more load capacity.

Does anyone remember seeing the Superlifts (RPO G66) in the assembly manual?

Thanks Tim! I always appreciate the help - that's very useful information. Agreed: like the helper springs, I'm not sure this setup will work for the K20 but it would be nice to have a complete setup up for another project (or maybe my brothers '66 tri-power GTO?).

Also, while looking through the lengthy thread on SPIDs I saw a couple listing the "superlift" shock option but came up short in a search for pics of trucks outfitted as such. I'd like to know a little bit more about this seemingly rare option. I do not recall any illustrations of superlift installs in the assembly manual.

I got the compressor yesterday and got it wired up to a 12 volt battery in the garage with jumpers. Cleaned the guage up and lubed the o-rings and got everything working. I just have to mount the compressor and a momentary switch to it. Hope to work on it this weekend.
The compressor is hardly loud enough to tell it's running but pumps pretty good.

[DeadheadNM]

Andy - Thanks for the helpful pic and the update. Keep us posted! Pete

[Andy4639]

Been in NC the last 2 days moving my Mom & Dad back home. Going to try and get on it again tomorrow.

[Andy4639]

Got out in the garage tonight for a little while. Got the relay that was with the compressor hooked up and running the compressor now like it's suppose to. Going to get started mounting the compressor tomorrow I hope.
Got to get a momentary switch for it and the hose. Waiting on it to come by UPS.
I'll take some pictures tomorrow of it installed I hope!
Thinking I will drill a small hole on the control panel and mount the momentary switch so it only comes on when I have my finger on it, this way no worry about blowing the bags out. Also want have any new dash holes either.

[DeadheadNM]

The momentary switch powers the compressor then?

I could put any kind of switch on it that I want now with the relay carring the load of the compressor the switch want see hardly any amps but I was scared if I put a toggle switch on it I would forget it and it blow the bags out.

The stock vacum pump is auto matic. Once the car is cranked the vacum pump will run until you turn the knob. Then it just shuts the vacum pump off.

[Andy4639]

Got the micro momentary switch done. Got the brackets all made up for the compressor. Hope to get more done later this week. Here are a couple more pictures for you.

[DeadheadNM]

Sweet....can't wait to see this hooked up!

[Andy4639]

I have to work the rest of the week and only have Saturday off. I have my consealed weapons class that day though, hope I can fit some more truck time in some where. Air lines should be here Wenesday or Thursday I hope.

[Andy4639]

As the lyric's of a old song go "I'm getting closer to my home"...
I got the compressor mounted and wired and got the pleasure-lift air gauge and momentary switch mounted in the truck this afternoon after work.I wired it and it works so all I need now is air hose and I'm good to go. I hope to be finished by Sunday.

[DeadheadNM]

Looking good! Have fun at the concealed carry class - I hope to have time for that soon myself. Pete

Yea it should be interesting with the wife who has never shot a gun before. bought her a .380 last week to use.

[Andy4639]

Class got cancealed family member had a car wreck and the shop owner cancealed. Going next Saturday now.

Got the air line kit but it was wrong so I'm back to square one again.

[Andy4639]

Well I got it done finally after searching for fitting for weeks I finally found everything I needed to get it going. Very pleased with it.I can pump the bags and dump the bags from the cab now!

[DeadheadNM]

Too cool!!!! Congrats! I was about to PM ya' to see how things were coming along. When possible I'd like to see a larger field of view pic of your dash with the mounted controller. Any advice you can share on the fittings would be appreciated. Pete

[DeadheadNM]

Never mind on the pic I just saw post #42...

The rear fittings of the guage and knob were the trouble ones. They are 3/16" and no one has them. I ended up doing a 3/16" union with 3/16" brake line with the 1/4" rubber hose with clamps on it. I just closed off the other side with a cap fitting. The rest was easy it all just went right together.
One major big change was the Park Ave compressor wouldn't even put pressure on the line so I ended up putting a cheap 12 volt compressor I had under the truck. It's noisy but it works. I may end up buying a compressor later though.

[Andy4639]

Just a follow up on this. I added a small compressor to pump the air bags with.
