To replace fuel injectors, you will need an assortment of common wrenches, a socket and ratchet set, a fuel line disconnect tool, screwdrivers, pliers, and protective safety equipment. It is important to note that replacing fuel injectors can be a tough and dangerous DIY job, so you may be better off having a professional do this one.
When replacing the injectors, it is also suggested to replace the injector washers every time the injectors are removed. This is because when the washer fails, a form of sludge and carbon deposit will form in the oil sump, blocking the wire filter at the end of the oil pump.
