Everything you need to install a big strong fuel pump in your tank. How much fuel is 325 liters per hour? Enough to empty the tank in a 1990 Miata in 8.5 minutes. Used as part of our Big Fuel kit and in our V8 conversions. Also suitable for high pressure applications such as cars running a boost-referenced fuel pressure regulator. We do recommend the use of a better fuel pressure regulator on NA models. Fits all 1.8 Miatas.
