CleanBoost® Diesel Rescue™ is the only formula out there that helps you INSTANTLY. All you have to do is follow the instructions. It instantly goes to work on re-liquefying gelled diesel fuel. It thaws out frozen fuel filters (that are mostly filled with ice, water and gelled fuel). It prevents fuel filter icing while removing water from the fuel system. Finally, it extends the life of frozen or gelled fuel filters, injectors and pumps.
