7 Color Light 2" 52mm Fuel Level Gauge with 0-190 Ohm Sensor for Marine RV Camper | Oil Tank Indicator 9-32V
Keep an accurate eye on your fuel or water levels with this 2-inch 52mm fuel level gauge and sensor kit. Designed for marine, RV, camper, and car applications, it works with a 0-190 ohm European standard signal and runs on a wide 9-32V power range. The 7-color backlight lets you match your dashboard style, while the IP67 waterproof build and anti-fog curved glass ensure reliable performance in tough conditions.
This gauge uses a moving-magnet principle and a stepper motor for smooth, precise readings with low power consumption. The included stainless steel fuel level sensor with float mounts directly into your tank to send real-time level data. Whether you are upgrading an old gauge or building a new setup, this kit gives you everything you need for clear, dependable level monitoring.
Installation is straightforward with a standard 52mm cutout size. The gauge face shows E, 1/4, 1/2, 3/4, and F markings so you can read your tank at a glance. The sensor length is designed to fit a wide range of tank depths, and the float moves freely to track changes in fuel or water volume. With durable materials and a wide voltage tolerance, this gauge is built to handle the demands of boats, RVs, and off-road vehicles.
Choose the package option that fits your project. The full kit includes both the gauge and the sensor, while the gauge-only option is perfect for replacing an existing dash unit. Either way, you get a reliable, easy-to-read fuel level solution that works in fresh or saltwater environments.

Usage Scenario
Mark restores old fishing boats as a weekend hobby. His latest project had a cracked gauge that gave false readings, leaving him guessing how much fuel was left. He installed this 52mm gauge and sensor kit in about an hour. Now he sees the exact level at a glance, and the blue backlight matches his new dash LEDs. On his first trip out, the needle stayed steady even through choppy water, and the glass stayed fog-free as the morning warmed up.
Micro Comparison
Many basic fuel gauges use a simple air-core movement that can bounce or drift over time. This gauge uses a stepper motor and moving-magnet design for steadier readings and less power draw. The 7-color backlight also gives you more customization than single-color units, so you can match your existing dashboard theme without extra wiring or adapters.
