When your CP4 fails, it's best to switch out the entire fuel system, along with the fuel return line. This clears out all debris and stops any new fuel system parts from getting dirty.
Additionally, over time, rubber hoses can wear and become hard or brittle, especially on high-mileage vehicles. Signs of wear such as small cracks may appear on the inside of the hose, even if the outside looks okay. This injector return hose assembly services both sides and comes with a regulated return valve.
