Why Does Firestone Coil-Rite Air Helper Springs Come with 2 Air Lines

Question:

Install on F4155 shows two separate air lines. What if one leaks more than the other? Any way to equalize into one fill line?

Well you would not want either bag to leak! But you can use a T-fitting to run both lines to one line and fill the bags at the same time. However, if you want to be able to level the vehicle side to side, you would need two separate lines which is why they come with one for each air bag.

For a T fitting you can use # F3273-1. I also recommend a tube cutter # AL10530 to get a nice straight cut on the air lines. A cut that is not straight is more likely to leak.
