I purchased this part for my 2007 Mazda 3i. The car was having problems being started after getting gas. You would have to turn the key several times, and hold steady on the gas pedal for a minute or two after the engine started, or it would stall. The part was one of the easiest installs I've ever done. The entire process took less than 10 minutes. The only difference I'm seeing is that on the OEM part, the line is a harder plastic/pvc material that is molded into a specific shape, where as the Dorman replacement is more of a softer, pliable type of material, but installs nearly identical as the stock piece does. After replacing the valve, I took the car to the gas station, filled up, and it started without any hesitation. Great product overall, and a much cheaper price than local part stores.
