Review on 🔒 Fuel Tank Cap Assembly: Reliable and Efficient Product for Optimal Fuel Performance by Aaron Masek

I'm sure it's a great product, but as some have noted below, Toyota changed the gas cap for the 2009 Prius from a grommet to a threaded version mid-year. If your 2009 Prius has a threaded gas cap you will need part number 77300-75010: Toyota Genuine Parts 77300-75010 Gas cap. Unfortunately, Revain Automotive doesn't recognize this nuance. So if you order this gas cap in error, you will need to return it at your own shipping cost plus a 20% "restocking fee".
