The OBS trucks with a mechanical pump will run about 55psi at idle

I think this is a frame rail pump off a 2001.
The plan is to rig it up tk work off a hobbs switch and activate under boost to help maintain pressure.

Why not just get an air dog and be done?

It has one friend. This will be a helper that only activates on demand from manifold pressure.
