2009 Kenworth T8 series leveling valve problems

I have a Kenworth T8 series, installed a new leveling valve on the drivers side, and the passenger side started leaking. Replaced the passenger side with a used one. Before and after said problems, the airbags were/are overinflating. Truck psi wouldn't go over 100 psi. Swapped the supply and the delivery lines, and the truck reaches 120 psi but the airbags wont inflate.

 

It's on the 2nd drive axle, each leveling valve operates the 2 on the corresponding side. Clocked the same way the old ones were taken off. When the truck is running the airbags are inflated all the way, when you move the bar down, it doesn't go down, you can hear the dump going but the bags don't go down. You move the bar up, you can hear it air up more

 

I was able to reference the instructions for the leveling valves and the supply and delivery are in the right ports, but it does the same problem where the bags overinflate and the truck doesn't reach 100 psi. The leveling bar is pointed down where it should be dumping. The hissing like it is dumping is present but the bags stay overinflated
