It is a threaded pressure sender designed to convert engine oil pressure into a gauge signal for compatible 240–33 ohm oil pressure gauges.

Always confirm the existing sender specifications and gauge range before ordering. The sender resistance range must match the gauge or cluster it is being used with.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eReplace the sender if the oil pressure gauge reads incorrectly, pegs high or low, fluctuates without matching actual engine oil pressure, leaks at the sender body, has a damaged terminal, or fails diagnostic testing. Always confirm actual engine oil pressure before replacing the sender so a real lubrication issue is not mistaken for an electrical sender problem.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eConfirm the original sender is a \u003cstrong\u003e0–100 PSI, 240–33 ohm, 1\/8\" NPTF, 10-32 stud\u003c\/strong\u003e unit before installation. Use thread sealant only where appropriate and avoid over-applying it, since sender grounding and gauge accuracy can be affected on some installations. After installation, verify gauge operation and inspect for oil leaks at the threaded port.\u003c\/p\u003e\n\u003ch2\u003eAlternate \/ Superseded Part Numbers\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e279B-F\u003c\/li\u003e\n\u003cli\u003eStewart Warner 279B-F\u003c\/li\u003e\n\u003cli\u003eFaria 90519\u003c\/li\u003e\n\u003cli\u003eDatcon 02505-00\u003c\/li\u003e\n\u003cli\u003eMerCruiser 850362\u003c\/li\u003e\n\u003cli\u003eVDO 360811\u003c\/li\u003e\n\u003cli\u003eVeeThree \/ SeaStar IA15016\u003c\/li\u003e\n\u003cli\u003eSierra OP24301 — marine replacement reference for compatible 100 PSI systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eThe important match on this sender is the gauge signal, not just the thread size.
