[QUOTE="Strokersace, post: 131998, member: 622"] Bypassed the return side of the selector and going straight into the front tank. Working great for now. Pressure is holding at 65 better than it has in quite a while. My guess is the original Walbro I had in there was being limped along by the AirDog for quite some time and finally just decided to go. Still don't know what could have caused the restriction on the return side of the selector. Starting to wonder if it has something to do with the volume going back thru it since I have the fatory line from the motor and the AD return "y'd" and both are going through it together. Shouldn't make a dang bit of difference I'd think, but I've had this same issue to some extent twice now. Of all the OBS diesels I've had, this is the only one I've had problems with the selectors on. Also made another interesting observation tonight... Since installing the new Walbro today, it is a TON quieter than the other one EVER was. The 1st one was always louder than a stock SD pump and I could always hear it whining. This one I have to put my hand on it to even know if it's working. [/QUOTE]
