Dam, Im havin some trouble. I am running 4 1/2 valves, 1 8 gallon tank, and 1 viair 450. The rear pops up real nice Clark.Thefront is a different story. Both lift and dump valves are up front about 2 feet from the front bags. I goes up so dam slow. I checked all my connections, made sure that all the valves are in the right direction, made sure no line is pinched. No leaks. I let my compressor run for like 2 mins and it still goes up ass slow. The dump works fine and sounds like its dumping what I put into it. Its body dropped 3 inches and the top and bottom bag cups are 2" a piece. Anyone have any clue why the front is so slow? Ive tried everything. Help me out!
