Veratron Deep-Pipe Level Sender - 850mm - 90 to 4 OHM

The Veratron Deep-Pipe Level Sender – 850mm – 90 to 4 OHM is a precision fuel or coolant tank monitoring component designed for marine and automotive applications where accurate level indication is critical to engine performance and safety. As an experienced mechanic, you know that a failing sender creates phantom gauge readings, leading to overfill conditions, vapor lock, or worse—running dry without warning. This Veratron sender eliminates guesswork by delivering reliable analog resistance output across the full tank depth, making it an essential diagnostic and retrofit component for boats, RVs, commercial vehicles, and restoration projects.

Built to Veratron's marine-grade standards, this 850mm deep-pipe sender uses a float-arm mechanism that translates physical fuel or fluid level into proportional electrical resistance, ranging from 90 ohms (full tank) to 4 ohms (empty). The extended 850mm length accommodates deep fuel tanks common in larger displacement engines and marine vessels, where standard senders fall short. The robust stainless-steel or brass construction resists corrosion from ethanol fuels and saltwater environments, while the precision-machined float ensures smooth, linear tracking without dead zones or erratic needle movement on your dashboard gauge.

This sender is ideal for retrofit installations on vintage restorations, marine engine swaps, and commercial fleet maintenance where OEM replacements are unavailable or prohibitively expensive. Installation requires matching your existing gauge's ohm range (90–4 is standard for most analog gauges); verify your wiring harness compatibility before ordering. The compact 4-inch flange diameter fits most tank openings, and the 2.5-pound weight makes single-handed installation straightforward. Whether you're troubleshooting a stubborn fuel gauge on a classic truck or upgrading a boat's instrumentation, the Veratron Deep-Pipe Level Sender delivers the accuracy and durability that separates professional-quality work from temporary fixes.
