Air leak from the electric valve assembly under the front steps

I have air leaking from the electric valve assembly under the front steps.
The arrow in the second picture is where the air is leaking.
I can feel the air stream when I put my finger up there.
I have not yet removed the assembly to be able to get a closer look.
I am wondering if others have had problems with this pair of assemblies.
Sources for needed parts and repair suggestions are needed.
Procedure?
Anyone know what size the connectors are for the air line connections there in the event I want to temporarily plug the feed line to prevent air pressure loss? 

It appears that another problem of broken regulator adjustment caps was caused by Foretravel installing the regulator in such a position that the cap was able to collect rainwater and then it apparently froze causing the caps to rupture.  I can probably get along without the caps but, the regulators look cracked under the adjustment caps.  Probably need to find a couple of new regulators too.

Jon,
 
You can replace the 4-way air valve or you can take it apart like many have done.  Clean the parts and put it back together and you will probably find it is will work like new.
 
1) The 4-way valve has an exhaust port with a filter and modulating valve that prevents the slide or step from slamming.
2) There is one air pressure input port from the inexpensive pressure regulator.
3)  There is a port that extends air cylinder.
4)  There is a port that retracts air cylinder.

A 12-volt solenoid moves an internal sliding valve within the 4-way air valve.  12-volts moves valve.  When 12-volts is turned off the valve returns.
In one position, air pressure flows to air cylinder to extend cylinder and the exhaust port is connected to the other end of the air cylinder. In the other position, air pressure flows to air cylinder to retract cylinder and the exhaust port is connected to the other end of air cylinder.

Any idea who might have a couple of new regulators at a decent price?
