<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 226-666 is a precision reed switch fuel level sender designed for marine and automotive fuel tank applications. This sender features a 660mm (26-inch) float arm length and operates on a 240-33 ohm resistance range, making it compatible with VDO fuel gauges calibrated to this specification.

Key Features:

  • Reed switch technology for reliable, long-lasting performance with no moving contacts to wear out
  • 660mm float arm length for deep tank applications
  • 240-33 ohm resistance range (240 ohms empty, 33 ohms full)
  • Durable construction designed for gasoline and diesel fuel compatibility
  • SAE 5-hole mounting flange for standard installation
  • Tubular design protects internal components from fuel contamination

Reed switch senders use magnetic reed switches sealed inside a tube, providing superior reliability compared to traditional rheostat-type senders. The float moves along the tube as fuel level changes, activating different reed switches to vary resistance and provide accurate fuel level readings. This sender is ideal for replacement applications or new installations requiring the 240-33 ohm VDO standard.

Easy and convenient

Gave one star because I have yet to use the product. Everything so far, delivery and price has been excellent.

Good selection and service. It was an easy process to find the product I was looking to purchase

Will shop again

Ordered an Fabtech steering box skidplate, best price I could find on the net was Autoplicity. Price was better than all the 4x4 sites I checked. Item is shipping directly from Mfg, so really can't comment on shipping speed. Otherwise, transaction was easy and I really like the fact they accept PayPal.

so far so good

Instant email updates, easy website to navigate. I like that they have multiple payment selections to choose from.
