ADJUSTABLE FUEL PRESSURE REGULATOR
Send to friend
Allows you to tun in the best air / fuel ratio for your car. Add this and the new AIR INTAKE TUBE KIT, adjust your air fuel to optimum power and you can gain as much as 1.75 horsepower!! I strongly recommend that you purchase and install an Air / Fuel gauge on the car to get the proper fuel pressure setting. RMS sells the AutoMeter air fuel gauges for the wide band reading that is needed to set the proper power ratio.
