Oil Pressure Sender Relocation Kit:
The oil pressure port on a Miata is 1/8" BSPT (British Standard Pipe Thread) while most aftermarket senders are 1/8" NPT (National Pipe Thread). This adapter uses a braided steel line and an adapter block to relocate your sender to the fire wall where it is more accessible and less vulnerable. The block has 3 different ports to allow connection of multiple sending units such as gauges, data, and warning lights.

Longacre Accutech SMi Oil Pressure Gauge:
2-5/8” Fits into Spec Miata eyeball vents
0-100 psi Oil Pressure Gauge

Molded polycarbonate / ABS case
An electronic sensor is installed on the motor to drive the gauge - (no oil or fuel in the driver’s compartment for added safety)

Since oil pressure is so critical it has 3 set points.

You can set the first just below normal running pressure (say normal is 60 psi "set it at 50 psi" no damage there). At this point the LED comes on. Set the second at 35 psi. The LED flashes " you need to know here, possible damage. Set the third at 20 psi. Engine damage is likely here. At this third set point the LED continues to flashPLUS the gauge backlight starts to flash.It s hard to miss this day or night. It allows you to get the engine shut down before it blows up, saving you $$.

Can be used with 12 & 16 Volt negative ground systems
