So the vented loop is not fixing either issue? Where do you have it mounted? Did you call Jason at wakemakers to find out what he recommends?

The interesting thing is that initially, the front sac did not auto fill - I turned each pump on when I first put the boat in the water to make sure they were all primed and there was water in the fill hose all the way to the bag. Then I drove at 25 mph and looked all three fill hoses (there were no bags attached to any of them) and no water was coming out of each one so I thought I was good. Then, after I filled the bags and started emptying them, I noticed the front bag was taking a long time to empty. I suspected that it was autofilling while at rest so I dicsonnected the fill hose at the front bag and sure enough, water was coming out of it. I think that when I hit the empty switch, it created a suction/siphoning effect and was drawing water thu the pump, up and over the looped hose and into the bag.

That also sucks that the vented loop leaks while filling as I just mounted them above some electrical connectors so I think I better remount them somewhere else.
