Fuel Tank: Inspection

  1. Check the hoses and the pipes for cracks or damage.
  2. Check the fuel tank cap for proper operation.
  3. Check the fuel tank for deformation, corrosion or cracking.
  4. Check the inside of the fuel tank for dirt or foreign material.
  5. Check the in-tank fuel filter for damage or restriction.
  6. Test the two-way valve for proper operation.
