Description

You should replace a Subaru gas cap when the cap is no longer sealing the fuel system properly or is physically damaged. Here are the common reasons to replace the gas cap on your Subaru:

-Check engine light/EVAP code – A loose, damaged, or incorrect gas cap can cause an EVAP leak code such as P0455, P0456, or P0457.

-Damaged or cracked seal – The rubber gasket can harden, crack, flatten, or become brittle with age.

-Cap no longer clicks or tightens properly – If it spins without properly locking or does not produce the normal tightening clicks, it may not seal.

-Fuel smell around the filler neck – A poor seal can allow fuel vapors to escape.

-Damaged tether or cap body – Physical damage is a good reason to replace it.

-Missing gas cap – Driving without one can allow fuel vapors and contaminants into the system and trigger an EVAP warning.

-Incorrect aftermarket cap – Subaru’s EVAP system is sensitive to the cap’s sealing characteristics. A genuine Subaru gas cap is preferable because it is designed to provide the correct seal and pressure characteristics for the vehicle.
