This fuel level sensor uses the standard SAE 5-bolt mounting pattern, extensively used with the Radium Fuel Cell Surge Tank. Full stainless steel sealed construction with magnetic float. Resistance: 0 ohm empty, 90 ohm full Suitable for use with gasoline, diesel, water, and all alcohol based fuels including methanol, ethanol, E85, etc. NOTES: -All level senders are 0 ohms empty to 90 ohms full (common with many aftermarket gauges.) -Radium does not sell fuel level gauges, but a popular option is this Autometer Fuel Level Gauge -To test the sender, measure the resistance between the two wires while tipping the sender to allow the float to move. -If purchased with a Radium Fuel Cell Surge Tank (FCST), the sender will come pre-installed. -If the output of this sender is not compatible with your OEM fuel gauge, consider a resistance signal converter, FOUND HERE.
