Veratron Deep-Pipe Level Sender - 390mm - 240 to 33 OHM

The Veratron Deep-Pipe Level Sender – 390mm – 240 to 33 OHM is a precision fuel tank level monitoring component engineered for reliable fuel gauging in marine, RV, and automotive applications where accurate tank depth measurement is critical. If you've upgraded your fuel system with larger or deeper tanks, or you're building a custom vehicle with non-standard fuel containment, this sender becomes essential for real-time fuel status visibility on your dashboard. Unlike shallow-mount senders that struggle in deep tanks, this 390mm vertical design reaches fuel at the bottom of tanks where standard senders fall short.

This sender uses a floating mechanism suspended inside a 38mm diameter vertical tube to translate physical fuel level into electrical resistance output across a 240 to 33 ohm range. The float rises and falls with the fuel level, moving a wiper contact along an internal resistive element; as the float climbs, resistance drops from 240 ohms (empty) to 33 ohms (full), a linear signal that your vehicle's fuel gauge cluster interprets to display tank capacity. Baffle holes at the top and bottom of the tube dampen fuel slosh and vibration, preventing gauge needle flutter during acceleration, braking, or cornering—critical for accurate readings in performance driving or rough terrain. This design isolation also protects the sender internals from fuel aeration and turbulence common in deep tanks.

Mechanics and fabricators working on fuel system retrofits, tank replacements, or custom fuel cell integrations will find this sender compatible with any gauging system accepting the standard 240–33 ohm ohm resistance curve—check your vehicle's wiring harness and gauge compatibility before installation. The 390mm length accommodates deeper tanks commonly found in long-range build-outs, off-road vehicles, and marine fuel systems where standard 200–250mm senders cannot reach bottom fuel. Proper sender grounding and a clean fuel supply are essential for signal integrity; mount securely to prevent float bind and ensure baffle holes remain unobstructed by sediment or contamination.
