Fuel Filter Replacement

All engine mounted fuel filters should be changed at the same time. If the fuel is contaminated contact an authorized Detroit™ service outlet for further instructions. After replacing the fuel filters, the fuel system will require priming. Priming the fuel system includes the use of special tools. Authorized Detroit™ service outlets are properly equipped for this type of service. Never use the starting motor and fuel pump to prime the fuel system. Prolonged use of the starting motor and fuel pump to prime the fuel system can result in damage to the starter, fuel pump, and injectors.
