Installation Notes and Tips
Confirm the vehicle uses an in-line fuel filter with a 3-pin electrical connector and water-sensor connection before ordering. Review the exact model year and notes for your application, since fitment varies by platform and sensor configuration. For example, Fits 2010-2012 Mercedes-Benz GL350, In-Line; Fits 2010-2011 Mercedes-Benz ML350, In-Line; and Fits 2007-2009 Dodge Sprinter 2500, N/A. Verify connector style and sensor fittings during service, and replace the filter according to the vehicle maintenance schedule.
