MAINTENANCE 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. Figure 12 Filled Fuel Tank Before adding fuel, refer to How to Select Fuel Oil in the HOW-TO SECTION of this guide. NOTICE: 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. Galvanized steel fuel tanks, fittings, pipes or supply lines should never be used.
The fuel reacts chemically with the zinc coating to form powdery flakes that can quickly clog the fuel filters and damage the fuel pump and injectors. To prevent microbe growth, add a biocide to the fuel tank or primary fuel supply. Water accumulation can be controlled by using additives containing methyl carbitol or butyl cellusolve. Follow manufacturer's usage, handling and safety precautions. Open the drain at the bottom of the fuel tank every 30,000 miles (48,000 kilometers) to drain off any water and/or sediment. Every 120,000 miles (192,000 kilometers) 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. 58 All information subject to change without notice. DDC-SVC-MAN-0039 Copyright © 2009 DETROIT DIESEL CORPORATION
