The included sensor harnesses provide added flexibility during installation, and the mounting brackets ensure a secure fit in any vehicle's in-dash mount.

Lastly, think about the aesthetics of your vehicle's interior. GlowShift offers a variety of gauge styles, including the Tinted 7 Color Series and the 10 Color Digital Series, allowing you to match your factory dash lights or create a custom look. With GlowShift's range of options, you can choose a gauge that not only functions well but also enhances the appearance of your vehicle.

Installing the sensor

To install the sensor for your GlowShift Fuel Pressure Gauge, you will need to identify a suitable location in your vehicle's fuel system. The sensor can be installed on the fuel filter housing, fuel pump, or fuel rail. It is important to note that your vehicle may not have the same thread size as the sensor, so you may need to use a thread adapter for the installation.

Once you have identified the correct location, carefully connect the sensor to your vehicle's fuel system. Ensure that the sensor is securely attached and there are no leaks.

The sensor harness and power harness will need to be connected to the back of the gauge. The sensor harness is typically 9 feet long, while the power harness is usually 2 feet or 5 feet long. These harnesses utilize Plug and Play Connectivity, making it easy to snap them into the modular connectors on the back of the gauge. The extended wire lengths offer added flexibility during installation.

After connecting the harnesses, you can secure the gauge in place using the provided mounting bracket and hardware. The mounting bracket is designed to attach to the back of the gauge, ensuring a secure fit in any vehicle's in-dash mount. Make sure to follow the specific instructions provided by GlowShift for your particular model.

It is important to carefully review the installation instructions provided by GlowShift before beginning the installation process. Additionally, GlowShift offers detailed step-by-step installation videos and free lifetime technical support to assist you throughout the process.

Wiring the gauge

The wiring harnesses offer added flexibility during installation thanks to their extended lengths. The Plug and Play Connectivity feature further simplifies the process, allowing for easy snapping of the harnesses into the modular connectors. It is important to ensure that your vehicle has the same thread size as the sensor, and if not, a thread adapter may be required.

The wiring process also includes connecting the orange power wire to the factory headlight switch, which enables dimming of the gauge when the headlights are turned on. This dimming feature enhances visibility, especially during nighttime driving.

GlowShift's detailed installation instructions guide you through each step of the wiring process, ensuring a smooth and accurate setup. Additionally, their free lifetime technical support provides ongoing assistance for any queries or challenges that may arise during or after installation.

Mounting the gauge

The mounting bracket included with your GlowShift fuel pressure gauge is U-shaped and made of metal for extreme durability. This bracket attaches to the back of the gauge for a secure fit in any vehicle's in-dash mount.

The mounting hardware included with your gauge will vary depending on the model and where you choose to install it. For example, the Elite 10 Color Series gauge comes with a dashboard pod that mounts to your car or truck's dash or another flat surface in the vehicle. Other models may require you to purchase a gauge pod separately.

If you are installing your gauge without a gauge pod, GlowShift provides a mounting bracket and hardware for a secure installation. You can also purchase a gauge pod that fits your vehicle's make and model and swivel to position the gauge at the desired angle.

When mounting your gauge, be sure to follow the included installation instructions carefully. You may need to drill holes or make other modifications to your vehicle's interior to secure the mounting bracket or gauge pod.

Once you have installed the mounting bracket or gauge pod, you can attach the gauge to it using the provided hardware. Ensure that the gauge is securely fastened to prevent it from moving or vibrating while driving.

With the gauge mounted securely in place, you can now connect the sensor and power harnesses to the back of the gauge. These harnesses utilize Plug and Play Connectivity for easy installation.

Testing the gauge

Now that you have installed the GlowShift fuel pressure gauge, it's time to test it to ensure it is functioning correctly. Here are the steps you should follow:

• Turn on the vehicle: Start your car or truck and let it run for a few minutes to ensure the fuel system is pressurized.
• Observe the gauge reading: Look at the fuel pressure gauge and take note of the current reading. It should be within the normal range for your vehicle, which can vary depending on the make and model.
• Compare the reading to a baseline: Compare the gauge reading to a known baseline or specification for your vehicle. You can usually find this information in the owner's manual or by consulting a mechanic. If the reading is significantly different from the baseline, the gauge may not be calibrated correctly.
• Check for leaks: Inspect the fuel lines and fittings to ensure there are no leaks. Leaks can affect fuel pressure and cause inaccurate readings.
• Verify the gauge's accuracy: To ensure the gauge is accurate, you can compare it to a mechanical gauge. Attach a mechanical fuel pressure gauge to the fuel line and compare the reading to that of the GlowShift gauge. If they are significantly different, the GlowShift gauge may need to be calibrated or adjusted.
