Air leak

I detected an air leak in the air distribution manifold. Does anyone know where I can find a new one? I did a forum search and did not find a thread in the Alpine forum. Thanks.

...might check the ACA technical library on our website for supplier references but pretty sure the air systems on the earlier Alpines were Haldex or other std large truck/semi components....which manifold is leaking?.....is it the manifold body or a hose connection?

Old Scout,
I did not find the distribution panel listed in the ACA library. You can see the small crack near the mounting tab.

Mark each line so you can return them to their correct position.


Push in on the "collar" to remove the lines.


Take the manifold to any OTR truck parts house for a replacement.

I fixed my air leak today. I installed an aluminum air manifold that is rated to handle the pressure

Great job. A proper manifold now in its place.

A little hard to tell in the photo, but it looks like you are putting more of a strain on the air lines by having them enter the manifold "horizontally" rather than from "below".


If that is so, how about mounting the new manifold on an angle iron so the lines enter from below as they originally did?


I know the lines are somewhat flexible, but the less strain the better.

The mounting holes only allowed for mounting in the pictured orientation. I could drill other mounting holes but I am concerned about nicking the air chamber. Thanks for the observation.

Scott,


My though was not to modify the manifold, but to use a piece of steel or aluminum angle (any box store). Mount it to the bulkhead and then the manifold to it.



That would allow the air lines to be more "fair-lead" as they were originally.

Brett,

I was thinking of using an angled piece to change the orientation after your last comment. I will look for a piece of angle that will work. Thanks.
