Fuel Sensor for alarm panel?

[egaito]

Working on something completely unrelated, I noticed a sender T'd into the line at the engine mounted fuel filter.

The sender, has three terminals, with two wires going to it, much like the other senders that feed the 12 point monitor.

Looking at the 12 point system monitor however, I see nothing related to fuel.

Any ideas what this sender is sending, and where it is sending it?

Thanks,

Power to the hourmeter

That might just work out....I've got new hourmeters to install, and was wondering where to put a switch so they only run with the engines (rather than the ignition switches)
