226-640

The VDO 226-640 Reed Switch Fuel Sender is a high-quality automotive component designed for accurate and reliable fuel level sensing in diesel applications. This sender features a reed switch technology, which utilizes a magnetic field to detect the fuel level position within the fuel tank.

The sender body is made of durable and corrosion-resistant materials to ensure long-lasting performance even in harsh environments. It is designed to fit and function in diesel engines, specifically those requiring a 400 ohm sender resistance. The sensor is designed for use with a float arm and cable assembly, which is not included in the package.

The VDO 226-640 Reed Switch Fuel Sender operates on a simple principle. As the float moves up and down with the changing fuel level, it activates the reed switch, which sends a signal to the fuel gauge. This signal is then interpreted by the fuel gauge to display the current fuel level.

The sender is easy to install, with a plug-and-play design that connects directly to the wiring harness. The package includes the sender body and the gasket, which is used to seal the sender to the fuel tank.

This VDO Reed Switch Fuel Sender is a reliable and cost-effective solution for monitoring fuel levels in heavy-duty diesel applications. Its robust design and magnetic sensing technology ensure accurate and consistent readings, providing peace of mind for vehicle operators and maintenance personnel. Whether you are working on a construction site, a logging operation, or a long-haul trucking fleet, the VDO 226-640 Reed Switch Fuel Sender is an essential component for maintaining optimal vehicle performance and efficiency.

Ground - floating. This revolutionary design comes with many benefits. The float less fuel sender has no side to motion, which means it moving parts wear out. Fits tanks with a depth of 15.75 400mm.

Reed switch fuel sender - 400mm. Works with most standard marine fuel gauges. Sold as an individual. Most aftermarket fuel senders use a rotating float arm and resistance cards to measure the amount of in tank which can lead erratic pointer movements.

This is ideal for applications where a conventional swing arm will not fit due to clearance issues. The tubular design acts as a dampener to prevent the gauge pointer from moving due fuel slosh. It is top mounted and utilizes the aftermarket standard sae 5 hole mounting flange comes complete with neoprene gasket hardware. 240-33 ohm range.
