Rebuilding a diesel vacuum pump can be a very time-consuming and frustrating job if you don't have the right instructions, tools, and equipment. What should only be a 2 to 3 hour job can easily become an all-day "big wrench dance. It can begin with rounding out the heads of the hex head bolts that hold the pump to the engine block, then proceed to fighting to remove the diaphragm from the pumping mechanism, and even ending with having to do it all over again because you did not put the pump together properly.
