Hagen Brothers farms,Goodrich ND | From what reading I have done on the net about lack of lubrication from ULSD unless a lubricity additive is added,fuel lubed pumps are not the only problem. ALL injectors used with both fuel and oil lubed pumps are fuel lubricated and can have severe wear if the fuel lubricity is not up to par,so an engine with an oil lubed pump is still in danger if the fuel does not have enough lubricity. :( |
