I have linked a diagram that shows the procedures listed below that go step by step in how to fill your Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter item # RP85FR with air.

1. Perform the hitching procedure before adjusting suspension air pressure, with the trailer loaded.

2. With trailer hitched to truck and landing gear / jacks retracted, add air to the air bag fill valve shown in figures 12 and 13. When filling the system, you must push the air valve into the hard stop to allow the system to take air (approximately 0.25”)

3. Fill until the Goosebox is at its nominal position (seen in the air inflation indicator) (figure 14)

4. It may be helpful to put tow vehicle in neutral to allow the unit to find its natural position. Then apply brake.

5. Recheck Air Inflation Indicator / inflate to desired ride comfort position.

6. The Goosebox is equipped with an automatic air relief valve. If you try to over inflate the bag, the relief valve will pop, releasing air.

Hi Jerred, my question is I over filled my airbag do to a miss calibrated air compressor. It caused the relief valve to release all the pressure. My question is will it automatically reset? And can I test filling the airbag not under load? Thanks

@LesH Yes, it will automatically reset. No, you'll want to hook it up, drive it around, and hit the brakes a few times to relieve that extra pressure. When you fill up the air bag you'll also want to be connected to your tow vehicle.
