Veratron Deep-Pipe Level Sender - 600mm - 90 to 4 OHM

The Veratron Deep-Pipe Level Sender – 600mm – 90 to 4 OHM is a precision fuel tank monitoring component engineered for accurate liquid level detection in marine and automotive applications. This sender replaces aging or faulty gauges that fail to report fuel status reliably, ensuring you always know your remaining fuel capacity before running dry on the water or road. Built by Veratron, a trusted manufacturer of engine instrumentation, this 600mm sender integrates seamlessly into existing fuel tank systems where dependable level measurement is non-negotiable.

The sender operates on a variable resistance principle, outputting between 90 ohms (empty) and 4 ohms (full) to drive analog fuel gauges found on dashboards. Inside the 38mm vertical tube sits a buoyant float that rises and falls with fuel level, while baffle holes at the top and bottom minimize fuel sloshing and electrical noise—critical for stable gauge readings during acceleration, cornering, or rough seas. The 600mm depth accommodates deeper tank configurations common in larger vessels and trucks, while the stainless or corrosion-resistant construction resists fuel degradation and moisture intrusion over extended service life.

Mechanics and boat technicians favor this sender when diagnosing fuel gauge faults or upgrading tanks that lack proper level sensing. Verify your vehicle or vessel's gauge ohm range and tank depth before purchase—this 90–4 OHM unit must match your existing instrument cluster wiring. Installation requires tank access and basic electrical crimping; many users pair it with quality marine-grade sealant to prevent leaks. Weighing just 1 lb, it remains light enough for retrofit work without structural reinforcement, making it ideal for restoration projects, custom fuel system builds, and warranty replacements where OEM accuracy matters.
