1-1/2in Elec.Oil Press

The 1-1/2in Elec. Oil Press gauge from AutoMeter is an essential diagnostic tool for any serious automotive enthusiast or mechanic performing engine modifications, rebuilds, or performance tuning. Real-time oil pressure monitoring protects engine internals during high-RPM operation and break-in periods, where oil delivery to critical bearing surfaces becomes paramount. Whether you're validating a new pump installation, diagnosing bearing wear, or verifying cooling system changes after forced induction work, this electric oil pressure gauge delivers dependable analog readout at a glance.

This model features a 0–100 psi range with short-sweep needle response, making it ideal for carbureted and fuel-injected engines where pressure swings occur rapidly during throttle transitions. The electric sender design eliminates mechanical oil lines from engine block to cabin, reducing installation complexity and potential leak points compared to mechanical gauges. AutoMeter's proven analog meter movement provides stable, flicker-free readings without electronic interference—critical when working in high-vibration environments or vehicles with aggressive ignition systems and aftermarket wiring harnesses.

Builders installing this 1-1/2-inch diameter gauge will appreciate the compact panel-mount design with black face that integrates cleanly into custom dash clusters and engine bay monitoring stations. The electric sender thread directly into standard oil pressure ports found on most V-block, LS, and small-block configurations. Installation pairs seamlessly with 12V systems on street cars, race vehicles, and restorations where gauging engine vitals informs tuning decisions and prevents catastrophic bearing or camshaft damage.
