    RS9000\'s...Big pain in the a@#

    I just bought this blazer with rs 9000's on it with the in cab controller. When I push the button to pump them up they pump up and when I let off the button they leak down in a matter of 20 seconds. The front and rear both leak down at the same rate. Is this a common problem after a year or so? I looked at the fittings and I don't think rancho could have come up with a worse setup for them. Any help here?

    No, that's not common. Find out which ones leak and then re-do them. I say re-do them by cutting maybe 1/2" off the ends and get new O-rings and put them in. The originally installer must've half-assed it when he put them in. Maybe there is a small hole in one of the lines?? But I do agree that Rancho cheaped it when they included those plastic lines in there.

    since it leaks down front and rear at the same rate it narrows down where the problem is. Have you ever heard of pressure leaking back through the compressor? I took a few fittings off yesterday and cut some off then reattached them. I didn't even see any orings, Where do they go? would they stay in the fittings when I pulled the lines off? Mabey there is none on there, that could cause it!

    No, I never heard of pressure leaking through the compressor. You said you didn't see any O-rings, that is probably your problem. The O-rings go on the red tube and inside that black knob piece.
    Hey, go to my site and click on "Mods" section. Then click on RS9000 Incab install. In there you will see how the O-ring gets installed/where it goes and what it looks like.
