AEM started with a piece of 6061-T6 billet aluminum, and then CNC machined it into an awesome universal high-capacity fuel pressure regulator. The longer spring allows for a wide range of fuel pressure adjustment (40-130 PSI), which is perfect for boosted applications needing a 1:1 rate. Whether you are running race fuel or Alcohol, this regulator will be compatible with both.
The 1/8” NPT fitting will allow you to run a gauge to ensure pressure is dialed in. Some other important fittings are the 3 -6AN inlet ports, which are used for 2 inlets, and 1 return. The vacuum port is a 5mm hose, which can be easily hooked up.
