When I installed my Firestone 7500 on my 2020 F450 I came with two air valves so you could air up individually each bag . I have since bought a air compressor with a remote control or you can use your phone to check air pressure or fill/ air down . I mounted it in a large plastic battery box that sits under my RollNLock canister in the truck bed . Works good when hauling my 5thwheel. If we go to a slide in camper I’ll just relocate it underneath truck.

I have an almost identical setup on my F250. Several trucks with air bags in the past but the first that I added the compressor and phone app. Love the setup, especially when hooking and unhooking trailers with different loads regularly.

Easy to do and sure saves the compressor from moisture damage.
Thinking of running it to the fuel door area for ease of filling. Still thinking about that though.
If you plan on using the bags to raise / lower the truck when hitching / unhitching having the Schrader valves that far away doesn't make sense, IMHO. I routed the lines for mine up through the rear fender well and popped them out into the bed through existing holes in the bed side walls. For the times when the truck or RV / trailer is situated where I need to raise or drop the rear it is very handy to have a fill valve back where the hitch is. I can see everything that is happening and make adjustments on the fly. I have also found that for this scenario adding air to just one bag is plenty enough lift for the rear to hitch / unhitch.
The only purpose will be when towing the 5th wheel. It's not bad but there is just a litte drop when hooked up of 1 3/4" was going to do this a couple years ago but never got motivated enough.
I would of thought having the fill ports in fuel compartment area would of been best for viewing the lift of rear end. Plus would think after filling it the first couple of times would have the psi roughly known for best ride?
Tackled the airbags on the dually, wasn't to bad and the only thing that slowed me down was the carriage bolts were 3" long and should of been 3 1/2". Nothing that a trip to the hardware store didn't resolve. Filled them up and all connections nice and tight with no air leaks. I did order the T for one fill connections but placed it somewhere where I wouldn't lose it and I can't seem to find it but know I'll come across it sooner or later so for the time being the 2 fill ports are mounted on the rear hitch. Eventually it will get mounted in the fuel door area.
