This is my “Killer Tank”, designed to hold chilled water from my Killer Chiller. Notice the drain valve and transmission cooler mounting pads on the bottom. The tank is a cross-flow design with an inlet port on one side and an outlet on the other. The holes have not been drilled yet for mounting it to the bumper, but that’s what the big tabs on the end are for. The whole thing will be insulated prior to installation.
