Sending units provide the sensor signals that allow gauges in your 1966 Catalina to display accurate vehicle information. These components measure conditions such as fuel level, pressure, or temperature and transmit that data to the corresponding gauge on the dashboard. OPGI offers eight Sending Units designed to fit your vehicle correctly. From fuel level sending units to gauge sensors and related components, you’ll find quality parts from trusted brands including Intellitronix and RESTOPARTS to help maintain accurate vehicle monitoring and reliable instrumentation. Every purchase is backed by our Price Match Guarantee. Plus, with OPGI’s 60-day return policy, you can shop confidently when selecting parts for your 1966 Catalina. Orders ship quickly, or you can visit our Southern California showroom to see select components in person.
