Faria Beede 90511 is a dual-station oil pressure sender designed to transmit engine oil pressure readings to two compatible gauges. Current product listings describe it as a 0–80 PSI sender with 1/8" NPTF threads, American/US ohm resistance, and standard ground through the threads. It is intended for use with compatible Faria Beede oil pressure gauges in marine and related engine-monitoring applications.
Key Features
- Part number 90511.
- Dual-station sender for operating two oil pressure gauges.
- Pressure range: 0–80 PSI.
- Thread size: 1/8" NPTF.
- American / US ohm range.
- Works with 12V and 24V DC systems.
- Standard ground through the threads to the block; do not use Teflon tape.
Engine Compatibility
This sender is best matched by gauge system rather than by a specific engine family. Current listings support it for applications using compatible American-resistance Faria Beede oil pressure gauges where a dual-station 0–80 PSI sender with 1/8" NPTF threads is required.
Serial Number Fitment Notice
Serial-number fitment is usually not the deciding factor for this part. The key checks are gauge compatibility, resistance standard, pressure range, station count, and thread type. Confirm that your setup requires a dual-station, US-ohm, 1/8" NPTF, 0–80 PSI sender before ordering.
When This Part Needs Replacement
Replace the sender when oil pressure readings become erratic, inaccurate, intermittent, or stop registering on one or both gauges. It is also a smart replacement when upgrading or repairing a dual-station helm gauge system using the same sender specification.
Installation Notes
Install into the correct 1/8" NPTF port and confirm good thread-ground contact. Because this sender grounds through the threads, current listings specifically note not to use Teflon tape. Match it only to compatible American-range gauges.
Alternate/Superseded Part Numbers
One current marketplace listing cross-references this sender to Marine Power 456132. The cleanest ordering reference remains Faria Beede 90511.
Parts Desk Insight
With pressure senders, the biggest mistake is matching by thread alone. Two senders can screw into the same port but still read incorrectly if the resistance range or station type is wrong. For a clean match, confirm all four points: 1/8" NPTF, 0–80 PSI, dual station, and American/US ohm gauge compatibility.
