⚠️ Freightliner fuel filter location critical: Freightliner trucks with the fuel filter inside the frame rail require Denso 428000-5730, not this part. Verify your Freightliner’s fuel filter location before ordering. Please also verify your truck make, model, year, engine type (Detroit Diesel 60 Series / Cummins M11 / Mack), and existing starter part number before purchasing. Contact us with your VIN if unsure.
