263XHD pump rub hole. Sometimes hard to see.

This is a short clip of the famous pump rub issue that are common on the 263XHD found on the Duramax pickups as well as other vehicles. It shows how hard it can be to locate the source of the leak as many times it only leaks as the vehicle is moving and when its parked no leak can be found.
