Author Topic:   "Riding on Empty"

My 21 Walkaround has a 92 gal factory installed tank and I have Yamaha multifunction digital gauges. With 30 - 45 gals in the tank, my low fuel warning light flashes and the fuel gauge shows empty. There are two wires coming from the tank sending unit that could be hooked to the fuel gauge. You can use either one of the two wires, but not both. I have tried the other wire (as originally wired by the dealer) and the gauge was even more inaccurate. I would prefer the gauge show Ľ tank remaining when it is empty rather than what it is showing now. Ironically, there is a sticker on my instrument panel that warns that the fuel gauge is only accurate when the boat is at rest. Actually, it is more accurate when underway and on plane! I realize that most small boat fuel gauges are not that accurate, but this is ridiculous! Should I try a different sending unit or maybe another fuel gauge? Does the sending unit have any adjustments? I really don't want to spend $300 for a Floscan or Yamaha fuel flow meter. Any and all suggestions would be most appreciated. Thanks,
Steve

It's likely that one wire is ground and the other is the sender-to-gage wire. The gage-wire terminal on the sender should appear that its isolated or insulated from the surrounding metal mounting flange. You might e-mail Chuck Bennett at the factory for proper electrical connection.
