Veratron Deep-Pipe Level Sender - 290mm - 90 to 4 OHM

The Veratron Deep-Pipe Level Sender – 290mm – 90 to 4 OHM is a precision fuel tank level sensor designed for accurate, real-time measurement in marine, RV, and automotive applications. This sender is engineered to fit deep-sump fuel tanks where conventional senders fall short, providing reliable fuel gauge feedback that lets you monitor tank capacity with confidence. Whether you're building a custom fuel system, restoring a classic vehicle, or upgrading an existing tank setup, this sender delivers the accuracy and durability that serious mechanics and enthusiasts demand.

At 290mm in length, the deep-pipe design accommodates fuel tanks with greater depth, ensuring the float mechanism reaches the fuel surface even in challenging installations. The sender operates across a 90 to 4 OHM resistance range, which translates directly to gauge needle movement—empty to full on most aftermarket and OEM fuel gauge clusters. Inside the 38mm diameter vertical tube sits a precision float that rises and falls with fuel level, while small baffle holes at the top and bottom of the tube prevent fuel sloshing from causing erratic gauge readings. This damping design is critical for smooth, stable gauge performance during acceleration, braking, and cornering—eliminating the needle flutter that plagues poorly designed senders and ruins the driver experience.

This sender is ideal for custom fuel system builds, fuel tank replacements, and gauge restoration work on vehicles where factory senders no longer fit or function. Verify resistance range compatibility with your gauge cluster before installation—most modern gauges and aftermarket gauges accept the 90–4 OHM standard. Installation requires proper tank access and careful float positioning to ensure accurate zero and full-scale calibration. Weight of 1 lb makes handling straightforward, and the Veratron name ensures you're working with a manufacturer trusted across the marine and automotive aftermarket for over three decades.
