Engine Fuel Pressure Regulator Parts
A fuel pressure regulator manages how much pressure builds in the fuel system and sends or meters the excess so the engine gets a consistent supply. When fuel pressure wanders, the air-fuel mixture can drift lean or rich. Owners often fit an upgraded or adjustable regulator after adding a bigger pump, larger injectors or forced induction, or when they want finer control during tuning.
This page sits under Engine Components › Fuel Pressure Regulator and currently lists 2 in-stock products, 1 from AMS and 1 from BBK. The AMS Performance 08-15 Mitsubishi EVO X Fuel Pressure Regulator Kit in Black is listed for the Mitsubishi Lancer. The BBK GM Tuned Port 305 / 350 Adjustable Fuel Pressure Regulator Kit is meant for GM Tuned Port 305 and 350 engines, as its name indicates.
How to choose:
Confirm the kit matches your engine and fuel system layout.
Decide whether you need adjustability for tuning or prefer a set-and-forget unit.
Check that your existing fuel lines and fittings work with the regulator.
Plan to verify fuel pressure with a gauge after fitting.
Use the vehicle selector to pick your vehicle and see what fits.
