The product works. Took about 100 miles driving to reset the sensor. My only concern is how tight the lower hose connection is. If this fails down the road, it may be really difficult to take off that connection. It is in a very tight spot. Other than that, great value and glad I was able to install by myself. 
Es funcional. Con su instalación mi auto dejo de presentar los síntomas de "ahogo" después de cargar gasolina y el sonido que salía de la tapa de combustible.
