Sucicago Marine Fuel Gauge 2-1/16" (52mm) Black — 5-Selectable Sender Ranges, IP67 Waterproof

The Sucicago 2-1/16" (52mm) marine fuel gauge is a universal replacement instrument that displays tank level from 0–100% with five selectable sender ranges and IP67 waterproof protection.

If you're customizing a dash or swapping out a worn factory gauge on a boat, RV, or custom vehicle, this Sucicago unit offers a compact, direct-replacement solution. It connects to your existing fuel sender, supports multiple sender resistances so it fits most systems, and features a clear LCD with a smooth stepper-motor needle sweep. Rugged construction, color-adjustable backlighting and a wide operating voltage make it a versatile choice for 12V and 24V installations.

How do I match this gauge to my boat or vehicle's fuel sender?

The gauge accepts five common sender resistance patterns so you can select the one that matches your sender without modifying the sender itself. During setup, use the built-in selector to choose the correct ohm curve; the needle will respond proportionally to the tank sender. If your sender is uncommon, you can test resistance with a meter and pick the closest setting.

• Selectable signals: 0–190Ω, 240–33Ω, 240–30Ω, 0–180Ω, 10–180Ω
• Works with most standard fuel-level senders on boats, cars, and RVs
• Use a multimeter to confirm sender ohms before selection
• Wiring harness included for straightforward connections

Will this gauge survive marine conditions and sunlight?

Sucicago built this gauge to handle wet, dirty environments: it carries an IP67 rating for dust and water resistance and has a 316 stainless steel bezel to resist corrosion. The LCD and backlight are rated for typical dash exposure, and you can rotate through seven backlight colors to reduce glare or match dash lighting. For prolonged sun exposure, mount it under a dash lip or use a dash cover to preserve the finish and display contrast.

• IP67 waterproof and dustproof housing for splash and temporary immersion protection
• 316 stainless-steel bezel for corrosion resistance in saltwater environments
• Seven backlight color modes for visibility and dash matching
• LCD display plus stepper motor needle for readable, stable indication

How difficult is installation and setup on a custom dash?

Installation is designed to be straightforward for anyone comfortable with basic wiring and panel cutting. The gauge fits a 52mm (2-1/16") panel hole and includes a wiring harness and instructions; the unit runs on 9–32V so it's compatible with most 12V and 24V systems. Calibration is achieved by selecting the appropriate sender curve, and the smooth sweeping needle gives instant feedback during setup.

• Fixing diameter: 52mm (2-1/16") for standard dash openings
• Operating voltage: 9–32V (works with 12V and 24V systems)
• Plug-and-play wiring harness included for simpler connections
• Quick calibration via onboard signal selection—no extra tools required

What performance and warranty should I expect?

The Sucicago gauge uses a stepper motor for a steady, accurate needle and an LCD to show percentage from empty to full. It was engineered to outpace many factory gauges in sweep smoothness and clarity, especially in marine use. Sucicago backs the product with a one-year limited warranty and lifetime technical support to help with installation or troubleshooting.

• Indicating range: 0–100% reading of tank level
• Smooth stepper-motor needle for accurate indication
• 1-year limited warranty and free lifetime technical support
• Includes gauge, wiring harness, and installation instructions

Who is this for: this gauge suits DIYers, boat owners, custom-vehicle builders, and fleet managers who need a compact, durable replacement or upgrade for a fuel-level instrument. It’s especially useful when you require compatibility with multiple sender resistances, want corrosion-resistant materials for marine use, and prefer flexible backlight options to integrate into a custom dash layout.
