I have two tanks in my 31ss, the port fuel tank float seems to get stuck on empty reading after I've towed it. Tanks are usually at least half full. I'll lift the float assembly out of the tank, reinstall it and everything works fine. Never had the problem occur when running the boat. I swapped fuel guages and have eliminated them as the problem. It's definitely in the float assembly and it sticking or getting stuck on empty. Even put new wire connections on the wiring, definitely something to do with the float. I can't see if it's actually getting wedged to the bottom of the tank, by the time I remove the bolts and lift the assembly out, everything looks normal and float is intact... I move the float by hand and the guage reads just fine..... it's happened 3 times now and only after I trailer it.

What's causing this to happen? Any ideas?

Maybe it's time for the new style floatless senders. Here are some http://www.cpperformance.com/SearchR...CategoryID=270
