The fuel gauge in our 34' Barth Regency (950 jumps all over the place! The guy who works on it said to ask where he could find a fuel sending unit (whatever that is)...any ideas? Thanks, Susie

Fuel gauges generally are inaccurate. I always makes notes when fill up, and knowing the "safe" distance drive by miles. On big tanks 20 gallons usually is showing as "0" , not that 20 gallons on flat bottom my go into the corner during turn, and let the engine suck air.
