Radium Engineering Fuel Level Switch, 1/8" NPT

Radium Fuel Level Switch, 1/8" NPT

Application: Universal – fuel containers with a 1/8" NPT port, including Radium FST, MPFST, MPFST-R, FCST and FCST-X surge tanks
Part Type: Fuel level switch
Part Number: 20-0461

The Radium Engineering fuel level switch installs inside a fuel container through a 1/8" NPT port and provides a switched signal when the fuel level drops. That signal can drive a dashboard warning light, a programmable ECU input for engine safety, or lift pump on/off control.

The switch is made from corrosion-resistant stainless steel, is compatible with all fuel types and is supplied with 24" (610mm) long 20AWG flying leads.

Key Features

• Switched Output: Drives a dash indicator, ECU safety input or lift pump control
• 1/8" NPT Mount: Threads into a 1/8" NPT port inside the fuel container
• Stainless Steel: Corrosion-resistant construction
• Reversible Polarity: Remove the E-clip and flip the float to reverse the signal
• Flying Leads: 24" (610mm) 20AWG leads
• Fuel Compatibility: Suits all fuel types

Important Notes
