What to know before buying

Listing details to confirm

The listing calls this an electric gauge but also contains a separate description of liquid-filled mechanical gauges. That description conflicts with the named electric product, so confirm the precise gauge type and selected listing details before purchase. The listed 3.94-inch dimensions are also not the same as the title's 2.625-inch gauge size, and the feature text's accessory kit contents should be confirmed for the selected package.
