If you wanted to go the manual air route might I suggest looking for any of the larger engine Omega A estates.
My 2.6 CDXi has the same air assist shocks but the air lines route to a simple Schrader valve located in the boot floor. I normally keep 5 psi in the system which makes the back end (unloaded) the same height as any other Omega A estate.
I keep a measuring stick with that height marked and when I tow, or load up the boot I use that when putting air in (using a bicycle pump) until the same height is reached, however I have been told previously that I should never exceed 30psi as the bellows may just rupture.
I never put more than 15 psi even when I collected 0.5t of fire wood.

Might be of use to you.

This air system described above is basically the same as fitted to the Vauxhall Cavalier CD's in the mid 80's (would  be the Opel Vectra in Europe) - an air valve located on the lip of the boot aperture to manually inflate / deflate the rear suspension as required.

Yes, thanks, this sounds good. Hope this is what I bought. Let's see, should come on Monday. I report what I got.

I got today only shocks, tubes come next week. Shocks are GM 72119084. The air tube connector is something IK never seen. Perhaps standard pneumatic solution where hose just "clicks"?

It's a plastic fitting that pushes over the inlet on the shock, and is retained by a clip that looks a bit like a hairpin

I assume you have also ordered the plastic pipes from GM? They are supplied in various standard lengths and come with the connectors, which are 90° fittings, as Nick says, located with a cross spring clip. The ends of each pipe is flared and has an O ring which form the airtight seal. They will be self explanatory when you see them.

Yes from GM but like earlier told I do not know what I ordered, the seller just said that I need them. After having seen these shock connectors I understand that something  is needed to get air in and keep it there as well. I have to wait. The seller is always right...hopefully.

This is what the plastic pipes and connectors look like with self levelling shockers...... not exactly well up on getting pictures on here, but here goes......

Thanks for pic. How about connector orientation, to front?
