Installation Notes

Verify the vehicle’s pump style before ordering, especially on 2 line pump and shallow can applications. Confirm the listed notes for police, taxi, and late design exclusions where shown. Because no gasket is required and a strainer is not required, installation should be checked against the existing engine setup and fuel line configuration before final assembly.
