How Much does a Alfa Romeo 166 Fuel Pressure Regulator Replacement Cost?
The fuel pressure regulator on your Alfa Romeo 166 keeps fuel supply constantly pressurised at the fuel rail so your engine can run efficiently.
Fuel that doesn’t get used is returned through the fuel pressure regulator back to the fuel tank.
The fuel pressure regulator can spring a leak but, more commonly, it doesn’t maintain the proper pressure at the engine, and your car doesn’t run correctly.
The only repair is fuel pressure regulator replacement, and that’s a service AutoGuru can help you with!
