Veratron Deep-Pipe Level Sender - 280mm - 240 to 33 OHM

The Veratron Deep-Pipe Level Sender – 280mm is a precision fuel tank level measurement instrument designed for marine, RV, and specialized automotive applications where accurate gauge feedback is mission-critical. Built by Veratron, a trusted name in marine instrumentation, this sender bridges the gap between your fuel tank and your dashboard gauge, converting actual fuel volume into an electrical signal your gauge can interpret. Whether you're integrating aftermarket gauges into a custom fuel system, upgrading legacy tank instrumentation, or troubleshooting erratic fuel readings, this deep-pipe sender delivers the reliable signal transmission that separates guesswork from certainty.

The sender operates on a variable resistance principle: a float mechanism inside the 38mm diameter vertical tube rises and falls with fuel level, pivoting a rheostat arm that changes output resistance from 240 to 33 ohms across the full range. Baffle holes at the top and bottom of the tube prevent fuel sloshing from creating false gauge readings—critical for vehicles on uneven terrain or during aggressive cornering. The 280mm depth accommodates deeper fuel tanks common in auxiliary or auxiliary fuel cell setups, making this sender ideal for dual-tank installations, long-range expedition builds, or gravity-fed fuel systems where tank geometry demands a longer probe. Veratron's sealed float chamber design resists fuel contamination and electrical drift over extended service life.

Mechanics and fabricators favor this sender when retrofitting custom gauge clusters, upgrading mechanical fuel pressure systems to electronic monitoring, or replacing failed original-equipment senders. The 240–33 ohm resistance curve is engineered to work with standard automotive fuel gauge clusters and aftermarket programmable gauges calibrated to this range; verify your gauge's input specification before installation. Installation requires a dry fuel tank environment or complete fuel system drain to prevent spills and ensure proper float operation. This sender is particularly valued in restoration builds, competition fuel cell applications, and any build where precision fuel monitoring replaces guesswork and keeps you informed of your true remaining range.
