    Hey tombstone69,

    It's not in between the two tanks.
    It seems to go from main primary tank towards the dryer (I think).

    It's weird because it's constantly leaking air even though air brake test passes.

    Take a picture of the dryer assembly and the line where it comes out of the tank.

    The air dryer acts as a go between the primary and secondary before the air goes into service.In other words each tank should have a line going to the air dryer,the primary is the one with the protection valve. On the other side of the air dryer are the service lines.Is the dryer leaking constantly?

    The dryer is not leaking; just this valve that I took a picture of. Both the new and old part have that "weep" hole but I have not switched them out yet since its been very cold outside. Its a roll-off truck btw. Thanks for your input!

    Edit: I will get a picture soon!
