Watch Your Warning Light: Oil Pressure Sending Units
Is your oil pressure light flickering, or is your gauge reading dead zero? The Oil Pressure Switch (Sender) is the likely culprit.
Warning Light vs. Gauge
Switches (Lights): Simple on/off senders that trigger the red "Idiot Light" on your dash when pressure drops too low.
Senders (Gauges): Variable resistance units that drive a needle gauge.
NOS and NORS Quality: We stock authentic USA-made senders that are calibrated correctly for vintage gauges, unlike generic modern replacements that give false readings.
