This listing is for an FU60 Round Gauge - There are no cables, accessories or a sender included.

Per the manufacturer:
The FU60 Digital Fuel Gauge displays fuel remaining in gallons, liters or percent (0-100%) in tenths, fuel used (gallons or liters), fuel consumption rate (gallons/hr or liters/hr) and "Time-To-Go" in hours and minutes at current consumption rate (before tank is empty). The CruzPro FU60 digital fuel gauge is a plug-in replacement for your regular analog fuel gauge. No need for special flow sensors.

The FU60 works equally well with gasoline (petrol) and diesel engines and requires no "subtractor" unit to compensate for diesel bypass. It works with your standard fuel sender manufactured by VDO, Teleflex, Faria, GM, Stewart-Warner, Centroid THREE terminal senders, Aerotech and others to compute fuel remaining, fuel consumption rate, trip fuel and "Time-To-Go" calculations. It accurately computes fuel remaining even if you have odd shaped tanks (such as often found in boats).

You "train" the FU60 to learn your fuel sender characteristics and tank shape by calibrating the FU60. You do this once (at time of installation) by filling your tank and stopping up to 20 times to tell the FU60 what the sender output means in gallons or liters at each point. The calibration data is saved into a non-volatile memory which retains the information even if the power is turned off.
