Seems that this last time out my tanks were pulling "very" uneven while switch was set to Dual. I normally will have a little more pull from the port tank but on this trip I used about 3/4 of port tank and less than a 1/4 of the starboard tank. I did fill my gas tanks up before the trip and stopped when the pump shut off. I have heard of overfilling causing an issue like this.

Any advise on how I can fix this? I am going out this weekend and would rather not have this problem out there and would like my starboard tank to start pumping again.
