AEM X-Series Oil or Fuel Pressure Gauge Kit, 0-100 psi - 30-0301

The AEM 30-0301 is a 52 mm X-Series digital gauge that measures oil or fuel pressure from 0 to 100 psi (0-7 bar). The kit includes a 100 psi brass pressure sender.

Most street engines run well inside 100 psi of oil pressure. For higher-pressure systems use the X-Series 150 psi pressure gauge 30-0307.

Fitment and requirements

• Needs a 1/8 NPT port (or adapter) in the oil or fuel system for the sender
• Needs switched 12V power, a ground, and a 52 mm (2-1/16 inch) gauge pod or panel hole
• No vehicle-specific harness; check clearance behind the pod for the gauge connectors

What it does

• Measures 0-100 psi (0-7 bar), one fluid per gauge
• Large center LED readout plus a 24-LED outer sweep
• Face buttons for peak recall, warning thresholds and standard or metric units
• Auto-dimming display
• 0-5V analog output and AEMnet CAN for logging
• 52 mm (2-1/16 inch) body, 0.825 inch deep

What is in the box

• X-Series gauge with black bezel and black face
• Power/IO cable
• Mounting bracket and knurled nuts
• Butt connectors

Frequently asked questions

Does the AEM 30-0301 come with the pressure sender?

Yes. The AEM 30-0301 kit includes a 100 psi brass pressure sender.

Can the 30-0301 read fuel pressure instead of oil?

Yes, as long as the fuel pressure stays within 0-100 psi. One gauge reads one sender.

Can I log the AEM 30-0301 with an HP Tuners MPVI4?

Yes, with extra hardware. Wire the gauge 0-5V analog output into the PROLINK+ cable (sold separately), which brings external 0-5V signals into VCM Scanner, and enter AEM's pressure scaling from the instructions. See the HP Tuners MPVI4.
