Anyone know how they work on a 50' Hustler? One of three of my tanks seems to stay full never moves.

I'll tell you how mine work...they're probably the same. My 50 has 3 tanks...1 center and 2 sides. All 3 motors draw from the center tank. My left xfer switch pumps fuel from the port tank to the center tank and the right switch pumps fuel from the SB tank to the center tank. Hope that helps...it took me running out of gas twice before I finally got them figured out.
