Where Do Firestone Ride Rite Air Springs Vent To When Using an In Vehicle Switch Panel  

Question:

A follow up to recently answered question, which I do appreciate. The Firestone Ride Rite documentation shows each switch with a DEL delivery port which is the port shown you etrailer pics with tubing. This goes to the airbags. The other port, SUP supply which you indicate is the port through which bag air is vented through on deflation, must be connected to the air compressor. It is logical that deflation air would vent back through this port but all pressure between it and the air compressor would have to be relieved to allow it to flow. How is this accomplished?

The air spring suspension enhancement systems when using a compressor switch like the Dual Function Air Spring Control Panel # F2188 will vent the air into the cabin of the vehicle. The air travels to the gauge to monitor the psi, and exhausts the air into the cabin directly behind the switch itself.

You can see in the attached photo of the Replacement Switch for Firestone Electric Control Panel # F9039 there are two connection points. The upper is the input of air into the switch and the lower is the exhaust to the air bags.

Thanks for the follow up and my apologies for any confusion. The upper connections that also run to the gauge are for the air input from the compressor or tank. The bottom connection fittings are the output to the air springs. When you press down on the switch, the air vents directly into the cabin/cab of the vehicle. I reached out to my contact at Firestone and there is not a direct fitting but rather just a valve it vents out so the released air cannot be vented outside the cab or cabin of the vehicle. I've attached a video of this installation to assist using the complete kit # F2168.
