Works/Fits great.
After a few thousand miles and several months it seems to be holding up fine. FYI: If you have these "Evaporative Emission Control System Leak Detected" codes (P0455, P0422, etc) coming up, the 'cheap guy' sequence is to re-tighten your gas cap & clear the code. If it comes back, replace the gas cap if it is over a couple years old, and clear the code. If it comes back, check the two valves first (purge valve & vent valve), especially if they are original and years old, as they have to open/close a zillion times and wear out. Purge valve is on top of engine, vent valve is underneath near the charcoal canister and gas tank. Both valves for my car were cheap enough to just replace versus trying to test them first. We also found a broken(completely off) port on the charcoal canister, leaving hose open to the air. So, to avoid the mechanic and the time/labor$ for 'smoke testing', do: gas cap, 2 valves, visual inspection first before you take it to a mechanic.
