Q: What is the typical installation process for this HEUI injector?
A: Installation requires mechanical expertise. The process involves removing the valve cover, disconnecting the fuel lines and electrical connector, removing the hold-down clamp, and pulling the old injector. The new injector should be installed with new o-rings and copper washers (not included). It is critical to torque the injector to factory specifications. We recommend professional installation to avoid engine damage.
