Veratron Deep-Pipe Level Sender - 450mm - 0 to 180 OHM

The Veratron Deep-Pipe Level Sender – 450mm – 0 to 180 OHM is a precision fuel tank sender designed for serious marine and automotive applications where reliable liquid level monitoring is non-negotiable. Built for mechanics and technicians who demand accurate gauge feedback, this sender translates float position into a clean electrical signal that drives your fuel gauge. Whether you're restoring a classic vehicle, upgrading an engine bay with modern instrumentation, or maintaining a marine propulsion system, this Veratron unit delivers the accuracy and durability required in professional service work.

The sender operates on a simple but effective mechanical principle: a float rises and falls with liquid level inside the 38mm diameter vertical tube, moving a wiper contact across a resistive element to produce variable resistance between 0 and 180 ohms—a standard range compatible with most analogue fuel gauges. The 450mm length accommodates deep-tank installations where shorter senders fall short, and the baffle holes at the tube's top and bottom dampen fuel slosh, preventing needle flutter and erratic gauge readings during acceleration, braking, and cornering. This design isolation also protects the float mechanism from debris accumulation, extending sender life and ensuring stable readings over thousands of hours of operation.

This sender excels in retrofit fuel tank work, custom fuel cell installations, and OEM replacements where the original sender has become unreliable or corroded. It's ideal for hot rodders, marine mechanics, and restoration specialists who prioritize gauge accuracy over guesswork. The 0–180 ohm resistance curve matches Veratron's gauge line directly, ensuring plug-and-play compatibility without additional calibration. Installation requires a standard sender bung or threaded mounting boss; always verify your tank opening diameter and thread specification before purchase. At just 1 lb, this sender adds negligible weight while delivering professional-grade reliability that mechanics trust.
