If your fuel filter cap / priming pump is failing, you may experience one or more of the following symptoms:

1. Hard Starting / Extended Cranking: Engine takes longer than normal to start, especially after fuel filter changes
2. Stalling After Start: Engine starts but stalls shortly after
3. Loss of Power on Hills: Noticeable power loss when climbing inclines
4. Rough Idle: Engine runs unevenly at idle
5. Diesel Odor or Wet Housing: Fuel smell or visible fuel seepage around the filter cap area
6. Air in Fuel System: Frequent need to bleed air from the fuel system
7. Excessive Smoke: Increased exhaust smoke due to improper fuel delivery

Our manufacturing and inspection processes ensure every fuel filter cap meets or exceeds Toyota OEM standards.

• Ensure the engine is cool before starting work
• Depressurize the fuel system before disconnecting fuel lines
• Clean the area around the filter cap to prevent contamination
• CRITICAL: Replace the O-ring and wet it with clean diesel before installation
• Inspect the filter housing threads for damage — replace if necessary

1. Depressurize the fuel system and disconnect the negative battery terminal
2. Remove the old fuel filter cap from the filter housing
3. Clean the filter housing sealing surface thoroughly
4. CRITICAL: Install a new O-ring and lubricate it with clean diesel
5. CRITICAL: Hand-start the cap threads to avoid cross-threading; tighten to specification — do not over-torque
6. CRITICAL: Prime the fuel system by operating the manual priming pump until it feels firm and fuel flows free of air bubbles
7. Open the bleed screw to let trapped air escape, then close it
8. Start the engine and check for fuel leaks
9. After a short drive, recheck for leaks

• Inspection: During routine fuel filter service (every 20,000-30,000 km). Check for cracks, warped threads, or a flat O-ring
• Replacement: Immediately if failure symptoms appear. This component should be replaced if the cap is cracked, threads are damaged, or the primer pump fails

• Packaging: Each fuel filter cap assembly is securely packed in protective packaging to prevent shipping damage
• Packaging Options: Neutral Packaging / OEM Brand Packaging
• Suitable for: Wholesale distributors, auto parts retailers, 4×4 specialty shops, commercial vehicle repair shops, and fleet owners
