With the injector-pump work done, move on to the rest of the intake swap. Remove the lower intake (don't forget to disconnect the wires for the heating elements), and clean the gasket surface. Install the new lower intake on the head, using a dab of Loctite on each of the retaining bolts. Install the rest of the hardware, including the air-temperature sensor and the fuel-filter bracketry. You can now separate the fuel-injector lines and install them on the engine, using the supplied clamp assemblies.
