Air suspension comoressor

[Lithiatwats]

So I have an 04 4x4 EB EXPY with air susp. Compressor is noisy in cabin after start which seems fairly common and suspension seems to be behaving. What I noticed in inspection is only 1 line going into 'back' of comp. I thought a 4x4 was supposed to have 2 lines? Is there something I'm missing? Could this be why pump seems to run for a long time (1 minute or so post start)

one line on my 2010 as well, might split somewhere in the back im sure. if you need a replacement I used Arnott.

There is one line. It's split somewhere else.

If it is noisy you most likely have a leak causing the compressor to work harder which is why it is failing. I new compressor will not last long. Consider finding the leak and replacing what is necessary when you replace the compressor or look into a coil spring conversion.

I have had good experiences with American Air Suspension.
