MANN-FILTER PU 927 X Fuel Filter

MANN-FILTER PU 927 X is a modern fuel filter insert designed for diesel engines, manufactured by the renowned German company MANN+HUMMEL. The MANN-FILTER brand, first registered on August 16, 1951, has been setting standards in filtration technology for decades. The company’s products are used in passenger cars, trucks, agricultural machinery, and construction equipment—often as original equipment (OE).

Application and Function

The PU 927 X filter is designed to clean diesel fuel of solid particles such as:

• Metal shavings

• Dust

• Combustion-related residues

• Contaminants resulting from corrosion in the fuel system

Its purpose is to ensure the purity of fuel delivered to the injection system, directly contributing to:

• Protection of injectors and high-pressure pump

• Maintaining optimal engine performance

• Preventing engine irregularities

• Reducing fuel consumption

• Extending the lifespan of the entire fuel system

Construction and Technology

The filter is made from high-quality filtration materials that provide:

• Large filtration surface

• High efficiency in separating even the smallest particles (as small as 4 µm)

• Resistance to aggressive fuel components

• Long service life and operational stability under varying conditions

The PU 927 X belongs to the modern eco filter category, meaning it contains no metal components. As a result, the filter is environmentally friendly and easier to dispose of after use.

Importance of Regular Replacement

The recommended replacement interval for the fuel filter depends on:

• Vehicle model

• Driving style

• Quality of refueled fuel

For many passenger and delivery vehicles, this interval typically ranges from 30,000 to 60,000 km. Regular replacement of the PU 927 X filter is essential to prevent:

• Clogging of the injection system

• Decreased engine performance

• Starting problems

• Increased fuel consumption

Vehicle Applications

The PU 927 X filter is used in vehicles from brands such as:

• Citroën

• Peugeot

• Ford

• Mazda

• Volvo

and others that utilize shared diesel engine technology, such as the 1.6 HDi and 2.0 TDCi units. The full list of compatible models can be found in the manufacturer’s or distributor’s catalogs.

Summary

MANN-FILTER PU 927 X is a reliable and durable fuel filter that meets the strict standards of vehicle manufacturers. With its efficiency and modern design, it is an ideal choice for drivers who seek maximum engine protection and low operating costs.
