Monitoring the Fuel and Fuel Tank

Monitoring the Fuel and Fuel Tank - Ops - #7621

To prevent fuel and fuel tank problems, the following measures are recommended:

  1. Keep the fuel tank filled to reduce condensation.
  2. Before adding fuel, .
  3. Refill the tank at the end of each day's operation to prevent condensation from contaminating the fuel. Condensation formed in a partially filled tank promotes the growth of microorganisms that can clog fuel filters and restrict fuel flow.
  4. Open the drain at the bottom of the fuel tank every 30,000 miles (50,000 kilometers) to drain off any water and/or sediment.
  5. Warning: PERSONAL INJURY

    To avoid injury from improper use of chemicals, follow the chemical manufacturer's usage, handling, and disposal instructions. Observe all manufacturer's cautions.

    Notice: Never use galvanized steel fuel tanks, fittings, pipes, or supply lines. The fuel reacts chemically with the zinc coating to form powdery flakes that can quickly clog the fuel filters and damage the fuel pumps and injectors.
  6. Every 120,000 miles (200,000 kilometers) or 12 months, tighten all fuel tank mountings and brackets. At the same time, check the seal in the fuel tank cap, the breather hole in the cap, and the condition of the flexible fuel lines. Repair or replace the parts, as necessary.
