This part cross-references Delphi FE0666 applications with 42022 and E16467 for the same application.

Common Problems This Part Can Address

• Hard starting caused by weak fuel pressure
• Engine hesitation under load from inconsistent fuel delivery
• Fuel starvation from a failing in-tank pump
• Low-pressure conditions that trigger drivability complaints
• Restricted flow from a worn or contaminated strainer

Installation Notes and Tips

Fits 2010-2014 Subaru Legacy and 2010-2014 Subaru Outback, in tank. Clean the fuel tank before installing the fuel pump to help prevent future seal problems.
