<h3>About VDO: A Legacy of Precision Automotive Instrumentation</h3><p>Few names carry as much weight in automotive instrumentation as <strong>VDO</strong>. Founded in 1929 and headquartered in Villingen-Schwenningen, Germany, VDO has spent nearly a century engineering precision measurement and sensing solutions for the global automotive industry. Today, VDO operates as a trademark of the <strong>Continental Corporation</strong>, one of the world's largest automotive technology suppliers, bringing the resources and R&amp;D depth of a global leader to every product in its lineup.</p><p>VDO's philosophy is grounded in three core values: safety, quality, and sustainability. Rather than treating these as marketing language, VDO embeds them into its engineering process — combining decades of manufacturing tradition with a forward-looking approach to vehicle technology. The result is a catalog of components trusted by OEM manufacturers and independent repair shops alike.</p><h3>What VDO Makes</h3><p>VDO's product portfolio spans both passenger cars and commercial vehicles, covering everything from climate control blower systems and fuel supply components to engine management sensors and vehicle diagnostics. The brand is particularly well regarded for two areas that enthusiasts and technicians rely on every day: precision <a href="/735-vdo-gauges-gauges-202044">gauges</a> and engine management sensors like the <a href="/735-vdo-gauges-mass-air-flow-sensor-5128">mass air flow sensor</a>.</p><p>VDO's <a href="/735-vdo-gauges-gauges-202044">gauge instruments</a> are among the most recognized in motorsport and street performance alike. From oil pressure and water temperature to voltmeters and fuel level gauges, VDO instruments are known for their clean styling, reliable internals, and accurate readings. Many builders choose VDO gauges not just for function, but because their analog aesthetics have become iconic in cockpit design.</p><p>On the engine management side, VDO's <a href="/735-vdo-gauges-mass-air-flow-sensor-5128">mass air flow sensors</a> reflect the brand's OEM heritage. Because VDO is a Continental company, its MAF sensors are engineered to meet or exceed original factory specifications — making them a go-to choice for technicians who want a direct-fit replacement without sacrificing the accuracy modern engine management systems demand.</p><h3>OEM Heritage, Aftermarket Availability</h3><p>One of VDO's most compelling qualities is that many of its aftermarket parts are manufactured to the same tolerances as the components originally installed on the assembly line. This OEM-grade quality standard means fewer comebacks in the shop and greater confidence for the DIY mechanic. VDO also supports its product line with service tools and vehicle diagnostics solutions, making it a comprehensive partner for professional technicians.</p><p>Whether you're building a custom instrument cluster, restoring a vintage European vehicle, or replacing a failed sensor on a daily driver, VDO's combination of engineering heritage and Continental-backed quality makes it a brand worth trusting under the hood and on the dashboard.</p>

Product Details

The VDO 226-640 is a precision reed switch fuel level sender designed for marine and automotive fuel tank monitoring applications. This sender features a 400mm (15.75 inch) arm length and operates with a 240-33 ohm resistance range, making it compatible with VDO fuel gauges and many other gauge systems.

Key Features:

  • Reed switch technology for reliable, long-lasting operation without moving contacts
  • 400mm arm length suitable for medium to large fuel tanks
  • 240-33 ohm resistance range (240 ohms empty, 33 ohms full)
  • Durable construction designed for gasoline and diesel fuel applications
  • Compatible with VDO fuel gauges and other instruments calibrated for this resistance range
  • Precision fuel level measurement for accurate tank monitoring

Reed switch senders use magnetic switches along the float arm for stepless, wear-free operation compared to traditional resistor card senders. This design ensures consistent accuracy over the life of the sender and eliminates common failure points associated with sliding contacts.

Quick checkout.

So far so good

I was lowering my Mustang and I was looking for a good deal. I looked around online and I found Autoplicity. I was surprised with the prices I saw. I thought it was another one of those fake websites that just take youre money and never respond, so I took the chance and ordered anyway. Dont be fooled by the cheap prices. This place is legit. Fast shipping and the package was packed so neat and looked great when it got here. Buy from these guys if you want to get a good deal. I highly recommend them.
