Installation Notes and Tips

Verify engine and fuel system configuration before installation, especially on USA market listings. Because no gasket is required and a strainer is not required, confirm the mounting surface and fuel line condition are clean and serviceable before fitting the pump. Always inspect the fuel lines, mounting area, and related components for wear or contamination during replacement.
