Hey guys. I am having an issue with my truckmount. It is spilling water from the water box. I do not have to have the key on for the water box to overfill. I have added some pictures to give a frame of reference, but basically it is pouring source water out of the hose pictured which originates form the cap pictured. admittedly, I know less than most about the actual mechanics of my truck mount. I would be grateful for any advice/guidance you can offer me. It just started happening and I have jobs tomorrow at 10am! So I am hoping I can keep frm having to run it in. Thanks so much in advance.
