The Fuel Filter P550372 is a high‑efficiency spin‑on fuel filtration element engineered to protect diesel fuel systems against contaminants like dirt, rust and particulate matter before fuel reaches the engine. It helps maintain optimal engine performance, reduces wear on fuel pumps and injectors, and supports reliable combustion in heavy‑duty applications.

Where It Is Used

This fuel filter is commonly used in:

Diesel engines for trucks and buses (especially older Volvo models)
Construction equipment and industrial machinery
Agricultural and heavy equipment
Systems where clean fuel is critical to injection performance and engine longevity

Key Functions & Features

Spin‑on design: Easy to install and replace during routine maintenance.
High filtration efficiency: Typically rated at 5 microns with ~99% efficiency to trap fine particles and protect fuel systems.
Durable media: Cellulose filter media designed for longevity under demanding conditions.
Standard fitment: Thread size and dimensions (e.g., M18 x 1.5 thread) allow compatibility with many diesel engine fuel modules.
Cross‑reference support: Works as replacement for equivalent parts like BF7644, FF5272, FC‑7102, LFF3584 and others from major filter brands.
