VDO Reed Switch Fuel Sender - 900 MM

The VDO Reed Switch Fuel Sender 900 mm is a marine-grade instrument designed to deliver accurate fuel tank readings on your boat's dashboard. Whether you're running a long coastal passage or a weekend fishing trip, knowing your actual fuel level prevents the anxiety of uncertainty at sea. This reliable sender is trusted by anglers and cruisers who demand dependable instrumentation when miles from the nearest fuel dock.

Reed switch technology has been the backbone of reliable fuel gauges across the marine industry for decades. These senders operate by moving a float arm across a series of electrical contacts as fuel levels change, creating clean, precise signal transitions to your gauge without the drift or noise that plague mechanical systems. VDO's construction ensures corrosion resistance in both saltwater and freshwater environments, with materials engineered to withstand the vibration, temperature swings, and moisture exposure inherent to marine propulsion systems.

This sender is ideal for retrofit installations on boats where factory gauges have failed or where tank depth may exceed standard sender reach. Installation requires tank access—either through an inspection port or by removing the fuel fill—and compatibility with your existing gauge harness. Always verify your boat's electrical system voltage and gauge type to ensure proper functionality.
