If I purchase the load lifter 5000 airline upgrade kit with a stainless lines, is there a T fitting available so I can fill both bags from one Schrader valve?

Hey Robert, what you'd need is an Air Lift Union tee part # AL21838 which would allow you to use a single inflation valve for both bags. I'm still a little surprised they don't just include this. What vehicle do you have?

The tea you recommend is for plastic lines, I was hoping to eliminate any of the plastic lines.

@RobertM I see what you mean now. So Air Lift and Firestone don't have any threaded styles of union tees. What they've told us in the past is that you have to run the plastic lines at the Tee and then the braided line past it.

Yes I bought them from you guys. It was awesome. I really like them. What I did is I used the braided line and I went from both sides of the bags to the rear bumper and I drilled two holes and put them on the outside of my bummer beside my license plate. What I did is I bought myself a pump and I put them up to the PSI recommended to carry my fifth wheel and it does really a great job. The only issue I really ever had is one bag is slowly leaking and we've been trying everything to make it not leak but it does. It's not bad cuz I've still got it. Good ride all the way to the RV park and once I get there I just let the air out of them where I can go back and forth to town. The tea idea is a great idea. That way you don't have to have one hole in your bumper. I hope this helps. I really enjoy them and I have no complaints at all
