We put together this special bargain priced gauge kit to go along with our custom adjustable fuel pressure regulators. We found these small gauges and fuel line adapters that will install right inline with your existing fuel line on your Mazda Miata or any vehicle with 5/16" fuel line. Having an adjustable fuel pressure regulator without a pressure gauge as a reference point is useless, as you need to know what your pressure is and what the responding air/fuel ratio is for that pressure.
