Are push-lock and compression fitting interchangeable?

So I mocked up my combination of GM Air Shocks and Delco Pleasure Lift today. One problem is that the shocks have one inlet each and get connected to a T; the Tee fitting, however, is a Shraeder valve so you can air it up with a tire pump.

Rather than the tire pump I need to connect it to the gauge/regulator in the cab. That means I need a T without the Shraeder valve so I can connect all 1/8" tubes as equals; one to each shock and one to the regulator.

I noticed that you can buy push-lock fittings in 1/8" and I'm wondering if, with this plastic tubing, you can use push-lock interchangeably with compression fittings. The pipe/tube looks the same to me, and it's rated for the pneumatic pressure, so other than perhaps not looking period correct, any problems with using push-lock?

I guess I shouldn't be surprised, but some of the little rubber o-rings in my 45 year old system are getting a little dry...

That's how I did mine. You can redo them as many times as you want you just need good straight cuts on the tubing.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Thanks Andy. When you say you did yours, did you combine a Power Pak with the Lift shocks? Anything else other than the T that I described require thought?

I did mine with helper air bags inside the springs. I have the old shocks that came with the kit when my dad gave it to me but didn't use them long before I dropped the truck. I took and ran the rear passenger side line to a tee then to the drivers side then to another tee. I then ran a shraeder valve at the back of the truck to use in case the compressor quit. I then ran the other two hoses to the compressor and gauge inside the truck.
