Crown Engineering Chem-Flush - 1 opens fuel lines that are plugged due to ice and sludge build-up. Chem flush - 1 can also be use to clean the filter pump and nozzle strainer when used as a full maintenance or tune-up product. Therefore, greatly reducing the number of service calls due to plugged fuel lines during the heating season.

Sid Harvey 050-B Cold Flow Improver,
,

Cold Flow Improver is used in cold climates when experiencing sluggish or slow-flowing fuel. Lowers the fuel's inherent Cold FilterPlug Point (CFPP) and Pour Point by preventing gelling and ice formation. Use in all grades of distillate and residual fuels. Refer to the Application Chart in the Complete Set for proper dosage rates. Available in retail packaging and bulk application containers. This product is EPA-approved for both on and off-road use.Sid Harvey Item #:050: Replaces Part #:'s : G80-598,
,

Technol 050 is a highly concentrated, unique severe cold climate distillate cold flow improver. Cold filter plug point (CFPP) is lowered by up to 30 deg F and the fuel's established pour point by up to 50 deg F. Technol 050 when used proactively, before the onset of cold weather at the ratio of 1:2000 will keep fuel flowing by preventing the formation of gelled fuel and ice blockages. If you are presently experiencing these blockages apply Technol 050 at the ratio of 1:200 to melt gelled fuel and ice, once melted Technol 050 will act as an"anti-freeze" preventing both the fuel and water from re-gelling and re-freezing. Be sure to protect your fuel and fuel system every time it is refueled by applying Technol 050 until warm temperatures arrive. Antigel agents permit fuel to flow smoothly even under the most extreme cold climate conditions. Anti-gel agents (cold flow improvers) are wax crystal modifiers that limit the size and modify the shape of wax crystals formed at temperatures far below the cloud point. Technol 050 should be applied directly to bulk storage or fuel tanks before the onset of cold weather. It is recommended to apply before refueling to ensure proper mixing and distribution.,
