Q: How to remove and replace fuel injectors and Fuel Rail on Toyota Tacoma?
A: To remove fuel injectors, relieve the fuel system pressure, and undo the battery. For V6 models, detach the engine cover, air filter housing, coolant, and intake manifold. Undo the vacuum hose, fuel lines, and electrical connectors. Remove the fuel rail and injectors, and get rid of the O-rings and insulators. Apply oil to new injector O-rings and install them.
