The Marine Fuel Sending Unit Fuel Gauge Sending Unit Fuel Gas Tank Sender Water Tank Sensor Water Level Gauge Sensor 250mm is a versatile product that is compatible with boats and RVs. The unit needs to be paired with a fuel gauge that will read the resistance to ground. Customers are advised to measure their tank depth and subtract one inch from the measurement for it to fit perfectly. The float size is approximately 1.370" in diameter, and it requires a 36mm hole saw for installation. The unit comes in several lengths, from 400mm (15.7") to 600mm (23.6"). Cutting the rod to fit is not advisable as it may damage the system inside the rod that sends a signal to the top before transferring it to the gauge. Overall the product is received positively, reviewers find it easy to install and accurate - additionally, it comes at a great price. However, some reviewers discover the measurements inConsistent; the sensor measures in eight steps, which means that changes aren't smooth, and there is no reading between 1/4 and E, suddenly dropping to empty. One downside was a case in which the fuel sender didn't work after installation, which was frustrating. **
