Directions:

To De-Ice Frozen Fuel-Filters
Water is dissolved in and carried by all diesel fuels. At temperatures below +32°F, water that has collected in fuel-filters freezes. This causes decreased fuel flow to the engine and results in reduced engine power or engine shutdown.

To de-ice frozen fuel-filters, check to insure that diesel fuel in the equipment fuel tanks is not gelled. If fuel is liquid:

1. Remove fuel-filters.

2. Empty remaining liquid from fuel-filters.

3. Fill fuel-filters with 50% Diesel 9•1•1® and 50% diesel fuel.

4. Reinstall fuel-filters.

5. Start engine.

6. If outside temperature is below +20°F, add Power Service Diesel Fuel Supplement® +Cetane Boost® as directed to prevent further gelling.

To Reliquefy Gelled Diesel Fuel
During cold weather operation, diesel fuel that has not been treated with Power Service Diesel Fuel Supplement +Cetane Boost can change from a liquid to a solid. This transformation is called gelling.

To reliquefy gelled diesel fuel:

1. Add 80 ounces of Diesel 9•1•1® to each 100 gallons of fuel in equipment tanks.

2. Remove fuel-filters.

3. Fill fuel-filters with 50% Diesel 9•1•1® and 50% diesel fuel.

4. Reinstall fuel-filters.

5. Start engine — let idle to warm up fuel system before resuming normal operations.

6. Add Power Service Diesel Fuel Supplement® +Cetane Boost® as directed to prevent further gelling.

To Remove Water from Diesel Fuel Systems
Diesel fuel systems accumulate water during normal operations. The constant recirculation of diesel fuel for lubrication and cooling of fuel injectors causes thermal variations within fuel tanks and produces water in the form of condensation. Water can also be introduced into a fuel system from fuel suppliers that do not periodically check their fuel-handling equipment for water contamination.

To remove water from a diesel fuel system:

1. Drain or pump water from the bottom of fuel tanks until diesel fuel appears.

2. Add 80 ounces of Diesel 9•1•1® to each 200 gallons of diesel fuel.

3. Remove fuel-filters.

4. Fill fuel-filters with 50% Diesel 9•1•1® and 50% diesel fuel.

5. Reinstall fuel-filters.

6. Start engine.
