Thanks for the post Glen67!

It's not entirely necessary to have the information from the unit to find a replacement pressure switch for you. I can't find any information on this Ram Air model anyhow.

What I'd recommend is to click on the below link to view our pressure switches.
1. Find the brand that looks like your original if you can (helpful but not necessary).
2. Click on either single-port or 4-port switches.
3. Choose the PSI rating you need (cut on and cut off pressures).
4. Does your original switch have an Unloader (Bleeder) Valve? Most switches do.

I think it's possible to find you a good replacement switch if you know the above specifications.

Glad to help if I can.

It sounds like you're describing the DE-2396329 pressure switch, or similar model, which you can see by clicking on the below link:

That switch has a cut-off PSI of 135, so you would need to manually adjust this switch to increase the cut-on PSI. This is all we have available but it does sound like this is the brand and type of pressure switch you have.
