P551625 Fuel Filter Kit 1884207C91 1884207C92 WF10066 PF9914KIT L7662FK PFF33286 FK22005 – For International 4300, TerraStar & IC Bus V8-6.4L
P551625 fuel filter kit for International 4300, TerraStar, and IC Bus V8-6.4L vehicles. OEM cross-reference verified. Orders from IXIN Filter.
Description
This P551625 fuel filter kit is a two-piece primary/secondary fuel filtration set engineered as a direct replacement for the Donaldson P551625, specified for the Navistar 6.4L V8 engine platform used across International 4300 trucks and a range of IC Bus commercial and school bus models. It’s designed to remove fine contaminants from diesel fuel before they reach the fuel injection system.
Product Overview
The P551625 fuel filter kit includes two filter elements engineered to work together — a primary and secondary filter — providing layered protection for the fuel system. As explained in this overview of how diesel fuel filters work, the primary filter handles bulk contamination and water removal early in the system, while the secondary filter sits downstream to provide fine particulate protection right before fuel reaches precision injection components. Rated for advanced-efficiency filtration at approximately 4 microns, the kit is designed to capture the fine particulate contamination that causes the most damage to modern high-pressure fuel injection components.
Because this is a matched two-piece kit rather than a single filter, both elements are included together as one product rather than sold as interchangeable individual parts. Each unit is tested for filtration performance before shipment — not just matched by part number.
