Mann+Hummel PU9361X Fuel Filter

Mann+Hummel PU9361X Fuel Filter

The PU9361X Fuel Filter is a high‑performance component engineered by Mann+Hummel, the world leader in automotive filtration solutions. Designed to meet the stringent requirements of modern internal combustion engines, this filter delivers exceptional protection against contaminants while maintaining optimal fuel flow.

Key Design Features

• Advanced Filtration Media: Utilises a multi‑layered cellulose and synthetic blend that captures particles as small as 0.5 µm, ensuring clean fuel delivery to the engine’s injection system.
• Durable Construction: The filter housing is made from high‑strength polypropylene with reinforced seams, providing resistance against pressure fluctuations and thermal stresses.
• Integrated Gasket System: A precision‑cut rubber seal guarantees a leak‑free installation on 84 mm diameter fuel lines, commonly found in VAG (Volkswagen Audi Group) vehicles.
• Optimised Flow Resistance: The filter’s geometry balances filtration efficiency with minimal pressure drop, preserving engine performance and fuel economy.

The PU9361X is specifically engineered for a wide range of VAG models. It is the OEM‑approved replacement for:

• Volkswagen Golf (V, VI, Plus, CrossGolf)
• Audi A3, A4, A5
• Seat Leon, Altea, Ibiza
• Skoda Octavia, Superb, Fabia
• Volkswagen Passat Variant, Golf V Schrägheck (1K1), Touran (1T1, 1T2)

Engine types covered include gasoline and diesel variants ranging from 1.6 L to 3.0 L, with both naturally aspirated and turbocharged configurations.

1. Safety First: Disconnect the vehicle’s battery and relieve fuel system pressure using a dedicated pump or by following the manufacturer’s procedure.
2. Remove Old Filter: Unscrew the existing filter housing, carefully detach the gasket, and discard the used filter cartridge.
3. Prepare New Unit: Inspect the new PU9361X for any manufacturing defects. Place a fresh gasket onto the housing’s inner surface.
4. Install Filter: Slide the filter cartridge into the housing, ensuring it sits flush against the gasket. Tighten the mounting nut to the specified torque (typically 15 Nm).
5. Re‑pressurise System: Reconnect the battery and use a fuel pressure gauge to verify that the system has returned to normal operating pressure.

• Enhanced Engine Longevity: By trapping fine particulates, the filter protects fuel injectors, pumps, and catalytic converters from premature wear.
• Consistent Fuel Flow: The low pressure drop ensures that the engine receives a steady supply of clean fuel, maintaining throttle response and power output.
• Improved Fuel Economy: Cleaner fuel reduces combustion inefficiencies, leading to measurable gains in mileage over time.
• Reduced Emissions: A cleaner fuel stream contributes to lower exhaust pollutant levels, helping vehicles meet stringent emission regulations.

The PU9361X’s filter media is composed of a blend of cellulose fibers and synthetic polymers that are recyclable under standard industrial processes. The polypropylene housing can be recycled in most municipal facilities, reducing the component’s environmental footprint.

• Manufactured in accordance with ISO 9001:2015 quality management standards.
• Tested to meet or exceed OEM specifications for pressure drop, filtration efficiency, and mechanical integrity.
• Certified under the European Union’s REACH regulation, ensuring safe use of chemicals within the filter material.

While the PU9361X is designed for long service life, regular inspection is advised:

• Check for visual signs of wear or damage on the gasket and housing.
• Replace the filter at intervals recommended by the vehicle manufacturer (typically every 30,000–50,000 km).
• Use a compatible fuel additive if the engine’s operating conditions demand additional protection against deposits.

The Mann+Hummel PU9361X Fuel Filter represents the pinnacle of fuel filtration technology for VAG vehicles. Its robust construction, precise engineering, and proven performance make it an indispensable component for maintaining engine health, optimizing fuel economy, and ensuring compliance with modern emission standards.
