The electrical lift pump under the car is easy to replace, the pressure pump is more difficult but any rate you need test instructions and repair procedures. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....
