That's the best price you'll probably ever find for a Autometer electronic nitrous pressure gauge. I bought a nitrous gauge, an electronic fuel pressure gauge and a dual purpose vacuum/boost gauge for my a-pillar pod.They arrived in a few days in perfect condition, NEW!
The gauges are old-stock, discontinued but brand new. They are now called the Lunar series and labeled as Autometer parts instead of Mr Gasket brand. The sending unit costs more than what he is selling the entire gauge assembly with a sending unit for.
