Description
The Speedhut 3-3/8″ Water Temp / Fuel Level (Dual Gauge) offers a practical solution for monitoring two essential vehicle systems in a single, compact unit. This gauge allows you to keep a close eye on your engine’s coolant temperature and fuel tank level, providing valuable information for maintaining your vehicle’s health and preventing unexpected issues. Designed for easy installation in a standard 3 3/8 inch (85mm) dashboard opening, this dual gauge combines accuracy with user-friendly features.
KEY FEATURES AND BENEFITS:
- Dual Functionality: Combines both water temperature (ranging from 120 to 260 degrees Fahrenheit) and fuel level (displaying from Empty to Full) readings in one gauge, saving space and simplifying your dashboard layout.
- Accurate Monitoring: Utilizes an internal microprocessor and stepper motor technology to deliver precise and reliable measurements for both temperature and fuel levels. This ensures you receive accurate information about your vehicle’s condition.
- Programmable Fuel Level: The fuel level portion of the gauge can be calibrated to work with a wide variety of aftermarket and original equipment manufacturer (OEM) fuel level senders with a resistance under 300 ohms, offering flexibility in installation.
- Configurable Warning Light: Features a built-in warning light that can be set to alert you when either the water temperature exceeds a defined high point or the fuel level drops below a specified low point, providing an early indication of potential problems.
- Straightforward Installation: Designed for easy mounting in a 3.33″ (85mm) diameter hole using a spin-lock ring. The included wiring harnesses simplify the electrical connections.
- Comprehensive Package: Ships with the necessary components to get you started, including a Speedhut temperature sensor and the required wiring harnesses for both the temperature sensor and the gauge’s power and lighting.

HOW TO USE:
- Mount the Gauge: Locate a suitable 3.33″ (85mm) diameter opening in your dashboard. Insert the gauge into the opening and secure it from the back using the spin-lock ring.
- Connect the Power and Lighting Harness: Connect the 3 ft Power & Lighting Harness to a suitable 12V power source in your vehicle. This harness will provide power to the gauge and its internal illumination.
- Connect the Temperature Sensor: Install the Speedhut temperature sensor in the appropriate location on your engine (typically a coolant passage). Connect the 2-wire temperature gauge wiring harness between the temperature sensor and the corresponding terminals on the back of the gauge.
- Connect the Fuel Level Sender: Connect the 2-wire cable wiring harness to your vehicle’s fuel level sender unit and then to the designated terminals on the back of the gauge.
- Calibrate the Fuel Level (if needed): Follow the Speedhut instructions to calibrate the fuel level gauge to match your specific fuel level sender unit. This typically involves setting the empty and full resistance values.
- Set the Warning Light (optional): If desired, configure the warning light to activate at specific temperature or fuel level thresholds according to the Speedhut instructions.
