Product Description

NF's amazing Fuel Guard is specially formulated to solve problems caused by water contamination in fuel. NF Fuel Guard is highly concentrated to make treating any fuel tank or bulk storage tank easy and affordable.

Fuel can be contaminated by water due to condensation in the fuel tank or from rain or other leakage into storage tanks. Adding NF Fuel Guard to the tank will dissolve the water into the fuel which means the fuel can still be used normally and the fuel tank does not have to be drained and the fuel disposed of. The water will simply evaporate during the combustion process and exit the exhaust as steam. Fuel Guard will also prevent and kill algae (also known as Fuel Bug) that grows in this water and can cause a host of problems in the fuel system.

Whether your fuel has been standing for a while and needs to be revitalised, or as a preventative measure to ensure fuel quality is maintained, add NF Fuel Guard to your fuel to solve water contamination and to prevent and kill fuel bug/algae.
