Key Features

- One-piece two-wire probe
- For matching 12V or 24V Racor detection systems
- Requires a compatible detection module
- Manufacturer part number: RK-21069
Product Compatibility
Match the bowl port, probe clearance and detection-module specification. This probe alone does not provide an alarm light or buzzer.
When This Part Needs Replacement
Replace a probe with damaged leads, a leaking body or a confirmed sensing fault. Inspect the connector and detection module when diagnosing a missing or persistent warning.
Installation Notes
Isolate power and fuel before installation. Use the correct seal and the module wiring diagram. Never connect the probe directly to supply voltage or to an unmatched detection module.

Parts Desk Insight
A matching thread does not make every water sensor electrically interchangeable. RK21069 is the two-wire probe type that needs a detection module; check the existing system before replacing an active sensor or ordering the probe alone.
