Product Details
Autobest F4443 is a performance-grade fuel pump and strainer set engineered for direct replacement use in select 1998-2004 Nissan Pathfinder and INFINITI QX4 models. It is designed for in-tank mounting and uses top-grade components that are tested throughout manufacturing for consistent output and fit.
