Function & Application:
The housing mounts in the engine bay and performs primary and secondary filtration of diesel fuel, removing water and contaminants before fuel enters the high‑pressure system. It is designed specifically for Volvo D13 Euro 6 engines in FH4 and FM4 heavy trucks and includes a hand priming pump and water separation stage. Correct, clean filtration helps protect injectors and fuel pumps and supports reliable starting and performance.

Condition & Testing:
This is a used original part in good working order. The housing was checked on the donor vehicle prior to dismantling; no visible leaks or cracks were present and the engine ran correctly with this unit installed. After removal the assembly received a basic external clean and visual inspection. Condition is graded B: normal operational wear, paint flaking and grime on the green housing, scuffs on the filter bodies and minor corrosion on fasteners, but all ports, threads and mounting points are sound. Used filter cartridges are included for reference but should be replaced with new elements during installation.
