Select a conve- nient location to mount the compressor. This location should provide ample air flow and be protected from airborne debris and moisture. The mounting surface should be rigid to sup- port the compressor.

Questions and answers
My truck,2014 Ford F250 SuperDuty, has model 2491 ride rite system mounted. It has only one pressure sensor mounted on the valve block. Worked OK but would not pump up over 20# of pressure. Just had air line replaced due to truck bed being removed due to cab body damage and repair. It now will run to approx 10#s and cut off? What do I need to repair system
To repair a Firestone 2491 Ride-Rite system that only reaches 10 psi, follow these steps:
1. Check for Air Leaks: Use a soap and water solution on all tubing connections. Look for bubbles that indicate leaks.
2. Inspect Tubing Connections:
- Ensure the tube is cut squarely.
- Push the tube completely into the fitting.
3. Remove and Reinsert Tubing if Needed:
- Release air pressure from the air spring.
- Push the collar of the fitting toward the body and hold.
- Pull the tube out and reinsert properly.
4. Check Electrical Connections:
- Make sure the red power wire is properly connected to the battery.
- Verify that pressure sender wires are connected correctly:
- Gray and Violet to LF/LR sender.
- Brown and Green to RF/RR sender.
5. Check for Faulty Pressure Sender:
- If one side is not inflating but the other works, inspect the wire connection on that side’s pressure sender.
These steps help identify and fix inflation problems in the Ride-Rite system.
