How to Replace a Fuel Regulator

How to Replace a Fuel Regulator

A cars fuel injection system supplies fuel to the engine. In order to get optimum performance from your vehicle, the fuel must flow at a steady pressure. Regulators control the fuel flow, making sure it is consistent. Like other mechanical parts, regulators can break down and require replacement. Symptoms of a faulty regulator include lower gas mileage, excess smoke from exhaust pipes and leaking oil from the engine. Replacing a fuel regulator can be a difficult task for inexperienced owners, but if you have basic car repair experience, you can save money and replace it yourself.
