Installed the intake manifold. I replaced the original with a dorman truck manifold. I added RTV around the top of the grommets out of habit, but the water intrusion issues on the LS trucks were from a bad hood to cowl seal. I don't think that will be an issue on my rig, but the upper plate is designed like a ramp to flow water right into the harness grommets. I figured it couldn't hurt.

I stripped down the fuel rails to clean, polish and reseal. Had the injectors rebuilt locally.
