Schaeffer’s Diesel Hot Line is an emergency treatment for gelled diesel fuel.
This quick-acting additive dissolves gelled diesel fuel back into solution and returns the flow in 20 minutes. Formulated with a unique blend of organic compounds, Diesel Hotline is recommended for use in all types of diesel fuel, especially low sulfur and ultra low sulfur diesel fuels.
It's a good idea to keep some on hand for those cold weather emergency situations!
