With a diesel vehicle, the fuel filter needs to be filled with diesel fuel before it is installed; if it isn’t, the vehicle will not start, Gaither said. It is recommended that the center of the filter be plugged before diesel fuel is poured into the inlet holes. Only then should the filter be installed on the vehicle.
