VDO Reed Switch Fuel Sender - 180mm

The VDO Reed Switch Fuel Sender – 180mm is a marine fuel tank instrument designed to replace problematic aftermarket senders that plague modern boaters with unreliable fuel gauge readings. After decades on the water, any experienced angler knows that erratic fuel gauges can turn a promising fishing trip into a cautious crawl back to the marina. This precision sender eliminates that uncertainty by employing proven reed switch technology, delivering consistent and accurate fuel level measurements across the entire tank capacity.

Unlike conventional rotating float arm designs that produce jumping needle movements and false readings, the VDO Reed Switch Fuel Sender uses a sealed magnetic reed switch mechanism that transitions smoothly across resistance values as fuel levels change. This solid-state approach eliminates the mechanical wear and contact corrosion that plague traditional resistance cards, ensuring your fuel gauge stays accurate season after season. The 180mm sender length makes it compatible with standard marine fuel tank installations, and the sealed design protects internal components from fuel contamination and moisture intrusion—critical factors for boats operating in saltwater or freshwater environments.

Boaters upgrading aging fuel systems, rebuilding engines, or installing new tanks will appreciate this sender's straightforward installation into tanks with standard filler necks and access ports. The VDO brand reputation for marine instrumentation means your fuel gauge will remain rock-solid, whether you're running a full-day charter, planning a multi-day offshore expedition, or managing fuel consumption during extended cruising. Proper fuel monitoring isn't just about avoiding empty tanks—it's essential for weight distribution, trim management, and making informed decisions about fuel stops and route planning.
