I just recently bought a 1998 ford mustang gt v8 4.6 liter with 100,000 miles on it. and it needs a new fuel pressure regulator. when we went to replace it we couldnt find it anywhere on the car, we dont know if we bought the wrong part because it doesnt look like anything on the car. I need help! could anything explain to me where to find it one the car or if they know a good website that has diagrams of the car.

Suggested Repair

Locate the fuel pressure regulator at the start of the fuel rail, usually toward the rear of the engine. It is a round cylinder where the fuel lines meet the rail and has a red vacuum line attached. Confirm why replacement is needed before installing a new part.
