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

My 4runner 140k miles threw out a catch code the other day. Having gone this route on other vehicles, before troubleshooting the entire evaporator system, I advise you to start with the simplest known solution. Purchase and install an original gas cap. After installing the original gas cap, the code disappeared and did not appear for several months. Hopefully this will fix your evaporator leak, if not then finding the leak in your system will be a big problem.
