Detailed Description

This Denso fuel pump and strainer set is built for vehicles using an in-tank electric pump arrangement. The included strainer helps filter fuel at the pickup point, while the pump supports steady fuel supply to the engine under normal operating conditions. It is a practical replacement for service work on Ford Explorer and Mercury Mountaineer platforms, including select Explorer Sport and Explorer Sport Trac models. This part cross-references Carter (e.g., P74178, P74203) for the same application.

Installation Notes and Tips

Confirm the vehicle’s build date, model year, and application notes before ordering, especially for 2002 Explorer Sport Trac and 1997-2000 Explorer Mexico-built exclusions.
