I know someone who's going to be in trouble if their wife reads the forum.

Ok - I didn't ask how long you had it so if you know the history and how it works then that helps. Mine had sat for a while and I had to feel my way around some creative engineering. Someone had added a feed off of the storage tank for air horns and also a manual valve behind the manual air feed (it must have been leaking).

What happens when you put 100 PSI on the tap line? Where does it go? It's either going somewhere or nowhere. That is, it's all blasting out of a giant leak (which you'd hear) or hitting a hard stop somewhere. Check for manual valves that might have been installed and may be shut off. Worst case is you may need to isolate the line for each bag and inflate them individually.

My bags are probably 30-years old and are holding up fine. It doesn't sound like the air is getting where it needs to.

Well air is either not pumping or if it is pumping it is escaping. One way or another... Which valve are you saying is not opening?

[4621_racing]

24 years old but have been under rear and no air escaping just can' get to air bags some type of restriction like valve not opening. Thanks Jimmy

[Steeljag]

How old are the air bags?

[Nomadac]

Your air bags may have weather cracks and leaking. I had to replace both of my rear air bags, plus the coating on the metal drum peeled off and caused it to leak.

We put 100 psi in tap line and it still will not air up but comp will run
