Quick facts
- Part: Standard Ignition PR434 fuel injection pressure regulator
- Fits: 2002-2007 Mitsubishi Lancer 4-cylinder 2.0L and other vehicles
- Material: Steel
- Condition: New
A worn regulator can show up as hard starting, a rough idle or poor fuel economy, and a fault elsewhere in the fuel system can look just the same. Before replacing it, look over the regulator and its connections with the engine off and cool for fuel wetness or a damaged O-ring, and leave any fuel pressure test to a shop. If a failed regulator is the cause, this one replaces it.
Fits
This regulator is a direct-fit replacement for the 2002-2007 Mitsubishi Lancer 4-cylinder 2.0L and the 2002 Mitsubishi Mirage 4-cylinder 1.8L.
