Step leak

Trying to figure out air step leakage. When step is out it doesn't leak, when in it does. You can hear it escaping directly under step. I used soapy water and found this brass t was leaking. I couldn't get it to stop, so I replaced. Still leaks, also from behind the brass fitting. I would like to replace the fittings on the air line itself like what is on there, or should I just replace with new sleeve or something else. I unhook the step from the arms so I can work under there, I could find leaks this way. But now it will only leak with step attached which gives me no way to locate. I like to keep step in at night, but it will loose air and then be out in the morning. I did use Teflon tape but was carefull, should a person not use it in this area?  Thanks again.

Teflon tape will not help you there. Best to replace all fittings.

It is usually recommended (on this Forum) to avoid using thread tape on air line fittings.  Thread paste is a more suitable product.
