How to replace the direct fuel injector (LAF) on GMC Terrain?

A procedure to replace the direct Fuel Injector (LAF) should begin with relieving pressure from the high side fuel system. Before Fuel Injector replacement be sure to mark their installed positions because the injectors feature alignment components. The next task involves removal of the fuel injection Fuel Rail assembly. After removing Fuel Injector retainers you must clean and check both Fuel Rail along with fuel injectors. Implementation requires installation of new retainers and correct placement of removed injectors according to previous position notes before adding the fuel injection Fuel Rail assembly.
