This universal fuel pressure regulator manufactured by AEM is ideal for heavy tunes on turbo engines. Its 1:1 ratio and its longer spring make it particularly precise and easy to adjust on a supercharged engines.

Entirely in forged aluminum, it has a large return orifice, which can withstand very large fuel flows. It is compatible with standard petrol, competition fuels and alcohols (methanol, E85, etc.) and can regulate fuel pressure from 2.5 to 8.5 bars. It has two inlets and one outlet with a 9/16"x18 thread (equivalent to Dash 6, or AN6), as well as a 1/8" NPT port for the connection of a fuel pressure gauge or  an optional banjo fitting..
