TOYOTA 22602-56350 Injection Pump Filter Sub-Assembly

The genuine Toyota 22602-56350 injection pump filter basket (FILTER, SUB-ASSY) is a premium-quality genuine OEM part responsible for protecting the fuel delivery system, specifically the fuel injection pump. This precision filter element prevents microscopic contaminants from entering the high-pressure system, safeguarding internal components from premature wear.

Technical Features and Functions:

• Part Type: Injection Pump Filter Basket / Pre-Filter Unit (Filter, Sub-Assy)
• Manufacturer: TOYOTA (Genuine OEM part)
• Material Composition: Chemical-resistant, high-tensile fine-weave filter mesh engineered to withstand the chemical effects of automotive fuel.
• Filtration Efficiency: High micron-level filtration performance to ensure maximum protection for high-pressure injection components.

Component Role and Symptoms of Failure:

The injection pump filter basket is installed directly in the fuel flow path. Over time, fine suspended particles can clog the filter screen, restricting fuel flow. A clogged or damaged filter basket can lead to the following symptoms:

• Power Loss: Insufficient fuel delivery causes the engine to lose power under load.
• Hard Starting: The fuel system cannot rapidly build up the required starting pressure.
• Rough Idle: Fluctuating idle RPM and engine hesitation or misfire may occur.
• Accelerated Injection Pump Wear: If the filter mesh tears, unfiltered contaminants directly cause abrasive damage to precision pump internals.

Replacing the filter when required is essential to maintain the long service life and operational reliability of the fuel injection system.
