Speedhut 3-3/8″ Oil PSI / Fuel Level Dual Gauge (R3-DG18-REV)

The Speedhut 3-3/8″ Oil PSI / Fuel Level Dual Gauge (R3-DG18-REV) offers a convenient and space-saving solution for monitoring two critical aspects of your vehicle’s performance. This single, high-quality gauge displays both your engine’s oil pressure and your fuel level, providing essential information at a glance. With a clear and easy-to-read display, you can stay informed about your engine’s lubrication and fuel supply, contributing to the overall health and safe operation of your vehicle. The inclusion of a warning light adds an extra layer of security by alerting you to potential issues with your oil pressure. Designed for a 3.28-inch mounting hole, this gauge integrates seamlessly into your dashboard. The comprehensive package includes all the necessary wiring and sensors for a straightforward installation process.

KEY FEATURES AND BENEFITS:

• Dual Functionality: Combines oil pressure (0-100 PSI) and fuel level (E-F) readings into a single 3-3/8″ gauge, saving dashboard space.
• Oil Pressure Monitoring: Provides real-time feedback on your engine’s oil pressure, crucial for preventing engine damage. The 0-100 PSI range offers detailed pressure information.
• Fuel Level Indication: Accurately displays the amount of fuel remaining in your tank, preventing unexpected fuel shortages. The E-F range is a standard and easily understood representation.
• Integrated Warning Light: Features a built-in warning light that can be configured to alert the driver to critical drops in oil pressure, allowing for timely intervention.
• Complete Installation Kit: Ships with all necessary wiring harnesses (2-wire and 3-wire), a 100 PSI pressure sensor, and a power/lighting harness, ensuring a comprehensive installation.

SPECIFICATIONS:

• Gauge Type: Dual Gauge
• Combo Options: Oil PSI and Fuel Level
• Oil Pressure Range: 0-100 PSI
• Fuel Level Range: E-F
• Size: 3 3/8 inch
• Hole Size: 3.28 inch (83mm)
• Warning Light: Yes
• Ships With:
• Wiring Harness (2-Wire Cable)
• Pressure Sensor – 100 psi
• 3 ft Power & Lighting Harness – for LED Lit Gauges and Clocks
• Pressure Gauge Wiring Harness (3-Wire Cable)

HOW TO USE:

1. Mount the Gauge: Locate a suitable 3.28-inch (83mm) diameter hole on your dashboard. Carefully insert the Speedhut dual gauge into this opening, ensuring a secure fit.
2. Connect the Pressure Sensor: Install the included 100 PSI pressure sensor to the appropriate port on your engine, typically where an existing oil pressure sending unit is located.
3. Wire the Pressure Sensor: Connect the 3-wire pressure gauge wiring harness between the newly installed pressure sensor and the corresponding connections on the back of the Speedhut gauge.
4. Connect the Fuel Level Wiring: Attach the 2-wire cable wiring harness to the fuel level sending unit in your fuel tank and connect the other end to the designated terminals on the back of the gauge.
5. Connect Power and Lighting: Use the 3 ft power & lighting harness to connect the gauge to a suitable power source in your vehicle (typically a 12V ignition-switched source) and to your vehicle’s lighting system if you desire the gauge to illuminate with your other instruments.
6. Verify Connections: Double-check all wiring connections to ensure they are secure and correctly matched according to the gauge’s wiring diagram (refer to the manufacturer’s instructions if available).
7. Test the Gauge: Start your vehicle and observe the gauge readings. The oil pressure should display the current engine oil pressure, and the fuel level should indicate the amount of fuel in the tank. Confirm that the warning light functions as expected (it may illuminate briefly upon startup).
