Thanks for the info,
the schematic does not look like how the boat is wired.
The engine is a westerbleke 27, The tank sender unit has three wires on it, and I think the gage has been replaced.
any ideas,

I don’t recall ever seeing a 3-wire sender.
An isolated 2-wire sender is wired per my schematic, with the addition of an insulated return/ground wire.

You might try searching or asking at the Nonsuch Yacht Owners Discussion List:

Can we see a picture of the top of the sender? any name or numbers on the sender?

3 wires suggests an aftermarket unit with a Pos. Neg. and switch for low level or water in the fuel. Do you have panel lights for low fuel or "Water in fuel?)

As always, please remember that even in a series of boats, seldom are two built alike. "new" production boats differ from this rule slightly though.

Yes, the there wire hookup from the sender had me wondering, good suggestion that possible after market unit. I will not be on the boat till next week will keep you informed, thanks again for the info so far..

Here’s a 3-Wire Fuel Level Sender, with Sense (Send), Pos. and Neg wires.
