How to fill Firestone airbags.

[articulate]

If you want you can make your air bag hold air better than that. It's going to take some time but it can be done . . . both time there is a slow leak in the bag itself.

The leak is slow, very, very slow. So slow that your standard method of spraying a little soapy water on the connections and bags didn't reveal the culprit. The thought of swapping out the bags isn't all the fun, but I see your point. Gracias.

if you plumb the bags together then the weight transfer from your vehicle will force air from side to side.Not really a good set up.

Must think beyond the air bags. I still have leaf springs. The bags aren't doing all of the load handling work. Additionally, while the air volume does shift from one bag to the other, the pressure remains the same in both bags at all times. It doesn't negatively affect the handling, and it's certainly better than going without the bags altogether.

I have mine plumbed together to help shift air between the bags when slowly four wheeling to help the articulation. I'm not worried about high speed cornering so this set up works great for me.

I have one air valve on my back bumper that use to air up/down the bags and monitor the presure. I run 5lbs when unloaded and 20 lbs when towing my KK trailer.

My 12V portable compressor works great when off road.

If plumbed together, use a small orifice in the line between the bags so that air pressure can travel back and forth, but not quickly. Like allowing a small leak between the two bags. That way, transfer of weight would happen far too fast for the bags to register, but sitting still for 5 minutes would equalize the bags. Similar to valving on shock absorbers.
