Fits Tank Depth: 18-1/2″. Collects fuel level information more consistently than swingarm senders. They achieve this by taking the measurement from the float – which is still a moving part. However, the fluctuation is much less because the range of motion is much less. Stainless steel construction provides efficient performance. A direct original equipment manufactured replacement. Calibrated to 33 to 240 Ohm’s. Sender length is 1″ shorter than tank depth.
