The 100TECH 16-158Ω fuel gauge is a precision marine-grade solution designed for boats, RVs, trucks, and diesel generators, offering reliable fuel level monitoring in demanding conditions. Built with a stepper motor movement, this gauge eliminates the erratic needle bounce common in traditional air-core gauges, ensuring smooth, accurate readings even in rough seas or on uneven terrain. The gauge is fully compatible with 16-158Ω resistive fuel level senders—simply connect it directly to your existing sensor for seamless integration. For optimal performance, it’s recommended to bench-test the gauge and sender together before installation to verify compatibility and calibration.

Constructed with an IP67-rated waterproof and dustproof design, this fuel gauge withstands harsh marine environments, including exposure to moisture, saltwater, and debris. The anti-fog treated lens and bright red LED backlight guarantee clear visibility day or night, while the 316 stainless steel bezel adds durability and corrosion resistance. The gauge features a 5-level dial marked with E (Empty), ½ (Half), and F (Full) for quick, at-a-glance fuel level assessment. Installation is straightforward, thanks to a threaded screw mount with a standard 2-1/16″ (52mm) cutout, making it adaptable to most marine, automotive, and vehicle dashboards. The included wiring harness and mounting hardware simplify setup, whether for boats, cars, trucks, or RVs.

Backed by a 1-year limited warranty and free lifetime technical support, this gauge is engineered for long-term reliability in industrial and outdoor applications. Note that this model is specifically designed for 16-158Ω resistive senders—ensure your fuel sender matches this resistance range before purchase. The package includes the fuel gauge, connector cable, and installation instructions, providing everything needed for a hassle-free upgrade or replacement.

Can this gauge be used with my existing fuel sender if it’s not 16-158Ω?
No, this gauge is specifically designed for 16-158Ω resistive fuel level senders. Always verify your sender’s resistance range before purchasing.
Why does the needle move in steps rather than continuously?
This gauge uses a stepper motor and reed switch sender, which inherently produce incremental (stepped) changes rather than a continuous sweep.
What’s the best way to test the gauge before installing it on my boat or vehicle?
Bench-test the gauge and sender together using a power source to confirm accurate readings and calibration before permanent installation.
