Oil Pressure Sender

The AutoMeter oil pressure sender (model 2242) is an electric pressure-sending unit designed for vehicles equipped with short sweep electric oil pressure gauges. This component bridges your engine's lubrication system and your dashboard gauge, translating real-time oil pressure into an accurate visual readout. Whether you're running a stock rebuild, a high-performance street engine, or a custom modification, reliable oil pressure monitoring is non-negotiable—it's your first warning system for bearing wear, pump failure, or circulation problems that can destroy an engine in minutes.

This sender features a 1/8-inch NPT male thread, the industry standard for engine block and filter housing installations, and operates across a 0–100 psi range with exceptional linearity and repeatability. The short sweep design pairs specifically with AutoMeter gauges calibrated to match its electrical signal curve, ensuring needle response accuracy without calibration guesswork. The compact form factor (5.7 x 2 x 7.7 inches) allows installation in tight engine bays, and the 0.41 lb weight places minimal stress on mounting brackets or plumbing. AutoMeter's construction quality ensures durability under thermal cycling and vibration common to performance driving and track use.

Mechanics and enthusiasts choose this sender for restorations, engine swaps, and aftermarket gauge installations where OEM senders are unavailable or incompatible. Verify your existing gauge is an AutoMeter short sweep unit before purchase—mixing sender and gauge brands or sweep styles will produce erratic readings. Installation requires a 1/8-inch NPT port on the engine block, filter canister, or adapter block; use PTFE tape on threads and torque fittings gently to avoid stripping. Pair with a compatible AutoMeter electric oil pressure gauge and appropriate wiring harness for a complete, reliable pressure monitoring system.
