Inspection of the Fuel System

Inspection of the Fuel System - Gen 5 DD15 - Ops - #7628

The fuel system should be inspected periodically. A good practice is to include the fuel system inspection as part of the pre-start inspection.

Inspect the fuel and fuel tanks as follows:

  1. Inspect all engine-mounted lines and connections for leaks.
  2. Visually inspect the fuel tank suction and return lines. Check for an accumulation of fuel under the tank.
    3. Notice: Keep the fuel tank filled to reduce condensation. Before adding fuel, How to Select Fuel. Condensation formed in a partially filled tank promotes the growth of microorganisms that can clog fuel filters and restrict fuel flow.
    Note: If any of the above conditions exist, it may be necessary to take the vehicle to an authorized Detroit™ service outlet.
  3. The water/sediment at the bottom of the fuel tank should be serviced as recommended in the maintenance tables using the appropriate engine duty cycle, Preventive Maintenance Tables.
  4. The fuel tank mounts should be inspected as recommended in the for the appropriate engine duty cycle, Preventive Maintenance Tables.
