This genuine Ferrari pipe links the diagnostic pump to the diagnostic pump filter on the California and California T. It maintains the correct vapour path within the EVAP system and prevents pressure-related faults and emissions warnings. With age, these pipes can harden or crack, causing leaks and triggering diagnostic errors. Replacing it with the correct OEM-formed pipe restores a proper seal and ensures the diagnostic pump operates as intended.
For a reliable, brand-new fit, we recommend you install a fresh screw collar during replacement.
