The fuel injector pump on our 2001 Ram 2500 diesel failed. The repair shop strongly recommended modifying the system to put a filter and water separator at the tank in order to ensure clean fuel gets to the pump. In doing so they say they have to remove the running board on the bed under the fuel filler. Wife is furious as she loves this truck and doesn't want it spoiled. Is there an easy way to put the board back on?
