Firestone Ride-Rite Coil-Rite Kit Leaking

[sciphi]

I put a Firestone Industrial Ride-Rite Coil-Rite air helper spring kit into the Fit's rear coil springs, and it has a slow leak. It'll leak down from 20 PSI to 10 PSI in 24 hours. So far I've put more slack into the air lines so they go into the push-lock (?) connectors straight on, Teflon-taped the tee compression fitting to make sure that's air-tight, and tested with soapy water to see any leaks. I can't find any obvious leaks. What else should I be looking at?

As an aside, the Air-Lift 1000 air helper spring kit in my Buick's rear coils holds its pressure for months without leaking.

Could be a small leak in one of the airbags. Spray some soapy water on them and the airlines and you might find the leak. Thats the method we use at work to find leaks on truck tires and rims.

Did you check the valve core?

Hmm, didn't think the bags themselves would leak. I'll give that a shot with the soapy water.

The valve core is tight. There's a spare that's going to be swapped in this evening.

We have had brand new airbags leak right after they were put on a truck, usually where the rubber is joined to the mount. The soapy water should do the trick for finding the leak.
