Anyone using an ultrasonic sensor?

I have looked at these SSI Technology Ultra Sonic Sensors.

QUESTION............

Before I head back to Lady KC,
I was wondering if anyone call tell me
where to find each of the two existing in the fuel tank sensors
and is it easy to remove their covers screws/bolts,
and then physically be able to remove the sensor assembly completely out of both the port and starboard fuel tanks.

What tools would be required to remove these fuel tank sensors.

Does anyone know if the existing in tank sensors are the 33-240 ohm type of resistive float arm.

Begining to wonder about the return on investment........lol

Can't answer the other stuff but in or around the cockpit step (at the forward end of the cockpit (port and stbd) you should find one or more round access ports, they screw out. Get a flashlight, screw them out and you should see the fuel hose connections and the level sensor attachments. My gauges are extremely inaccurate, I don't use them. Different model years have different access holes/locations.

The top of the tank connections on our TomCat are at the rear of the tanks nearest the stern. Access to this area is through the screwed in side storage areas. Once removed, the rear of the fuel tank is visible.
That is why the gauge reads empty at rest and 1/4 underway.

This is what happens when you have a bunch of companies building the same model of boat!

On the TC24 the access hatch is under the cockpit step. When opened the sensor units are immediately visible. Had to replace one this spring. I learned that you don't want to do this with a full tank of gas.
