Today I removed the access panel on top of the fuel tank in our eagle model 20 and found a fuel sensor on the top of the tank. But no gauge on the daash whats up with this. Is it prewired at the dash and all I need to do buy one to place in there.

This is kinda common in mass-produced busses. They'll put in the sender during manufacture but the gauge (the expensive part - and usually optional) isn't installed unless it's asked for. It's kind of a pain in the butt to drop a 100+ gallon fuel tank to put a sender in so it's done proactively (and some manufacturers put in an access hatch for the sender).

I would suggest that you check out the sender you found before putting too much effort into installing the gauge. When I ripped out the floor in my '84, I found a sender (to my surprise then...) but when I took a reading with a DMM (digital multi-meter), I found it to be "open". Upon pulling the sender I found very little of its inner workings left (the float, float arm, and potentiometer were all dissentigrated).

Typically the sender (if good) will read somewhere between 240 Ohms (empty) and 30 ohms (full) between ground (the tank) and the wire lug.

You will probably find that the gauge is pre-wired (check your manual, it's probably safely taped up in a wire loom somewhere in the dash :-) ).

My fuel gauge was inside the access door to the fuel fill on my NJT model 20.
