Review on Premium Black Fuel Tank Cap: Gates 31849 OE Equivalent - Guaranteed Quality! by Bryan Brant

Perfect fit for our car. The check engine light came on and the dealer charged us about $3,000 for parts and labor to replace a part that "might" need replacing. My friend then recommended replacing the gas cap, saying that this usually causes the check engine light to come on. We replaced the cap with this one, filled up the car and after about 60 miles the light went out. $35 vs. $3,000 for a car repair!
