Float-style fuel level sending units with standard SAE 5-bolt mounting pattern. Easy to install using the supplied hardware and Deutsch connectors (gauge not included). Fits most fuel cells including Radium, ATL, Fuel Safe, Pyrotect, Harmon, Jaz, etc. and extensively used with the Radium Fuel Cell Surge Tank. Unlike most other senders, this rugged design features a FR4 conformal-coated PCB, epoxy potted electrical terminals, and an anodized surface finish making it suitable for use with gasoline, diesel, and specifically alcohol based fuels including methanol, ethanol, E85, etc.
Made here in Portland, USA.
All level senders are 0 ohms empty to 90 ohms full. This 0-90 ohm range is common with many OEM 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.
Fuel level senders carry a 1 year warranty through Radium Engineering
If purchased with a Radium Fuel Cell Surge Tank (FCST), the sender will come pre-installed.
Not compatible with MS109E fuel.
ALWAYS MEASURE THE INSIDE DEPTH OF THE FUEL CELL BEFORE SELECTING SENDER LENGTH. If not possible, use the general guide below. NOTE: This is a conservative recommendation. Depending on the fill plate and bladder type, a longer probe may potentially work.
If using the Radium Spare Tire Fuel Cell, select the 8" long sender
