Starting top left is the hose coming from a hole drilled in the truck floor. I ran the Meth line though a vinyl tubing the entire way to the motor for protection. Used tube clamps under the car. Bottom left is after I brought the tube into the engine bay going into a check valve. So the Meth will not be pushed back to the tank. The last picture is of the nozzle into the cold side charge pipe about 6 inches before the throttle body.
