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:
-
Remove
fuel-filters.
-
Empty
remaining liquid from fuel-filters.
-
Fill fuel-filters with 50% Diesel 9•1•1® and 50%
diesel fuel.
-
Reinstall
fuel-filters.
-
Start engine.
-
If outside temperature is below +20°F, add Power
Service
Diesel Fuel Supplement® +Cetane Boost or
Arctic Express®® Diesel Fuel Antigel.
To Reliquefy
Gelled Diesel Fuel
During cold weather operation, diesel fuel that has
not been treated with Power Service Diesel Fuel
Supplement +Cetane Boost or Arctic Express® Diesel
Fuel Antigel can change from a liquid to a solid.
This transformation is called gelling.
To reliquefy gelled diesel fuel:
-
Add one gallon of Diesel 9•1•1® to each 100 gallons
of fuel in equipment tanks.
-
Remove
fuel-filters.
-
Fill fuel-filters with 50% Diesel 9•1•1® and 50%
diesel fuel.
-
Reinstall
fuel-filters.
-
Start engine — let idle for 5 minutes to heat fuel
system before resuming normal operation.
- Add Power Service
Diesel Fuel Supplement® +Cetane Boost® or
Arctic Express®® Diesel Fuel Antigel 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:
-
Drain or pump water from the bottom of fuel
tanks until diesel fuel appears.
-
Add one gallon of Diesel 9•1•1® to each 200
gallons of diesel fuel.
-
Remove fuel-filters.
-
Fill fuel-filters with 50% Diesel 9•1•1® and
50% diesel fuel.
-
Reinstall
fuel-filters.
-
Start engine.
