Radium Engineering Fuel Level Switch Plus Diagnostic Indicator for Radium MPFST FCST 20-0519

Radium Engineering Fuel Level Switch Plus Diagnostic Indicator combines both 20-0461 Fuel Level Switch 1/8 NPT and 20-0508 Fuel Level Diagnostic Indicator.

This switch is only compatible with the Radium Multi-Pump Fuel Surge Tanks (MPFST) and the Radium Fuel Cell Surge Tanks (FCST). Both of these products have specially machined ports that are labeled "Level Switch".

20-0461 Fuel Level Switch, 1/8 NPT

This 1/8" NPT fuel level switch should be installed inside the container. When fuel level drops, a switched signal can be sent to a unit such as a dashboard mounted indicator or programmable ECU input for safety purposes. The level switch is constructed of corrosion resistant stainless steel compatible with all fuel types. It includes 24" long, 20AWG flying leads.

NOTES:
1. Polarity can easily be reversed by removing the E-clip and flipping the float.
2. 1/8" NPT threaded port is required for installing.
3. Always apply PTFE thread sealant to tapered pipe threads. 

20-0508 Fuel Level Diagnostic Indicator

If the 20-0461 Fuel Level Switch is used, this 20-0508 Fuel Level Diagnostic Indicator can be used as a visual reference for fuel level. When the fuel level switch is triggered, the signal is sent directly to this LED. While often not practical to be viewed while driving, this indicator can be used for diagnosing a potential fueling issue.

NOTES:
1. A 2AN ORB (5/16"-24) threaded port is required for installing.
2. If stacking on top of the fuel level switch the panel thickness must be 0.75" minimum.
