Fitting and Operating

The L500 De-Bug Unit is the size of a typical filter housing and is easily installed to the fuel line before the primary filter. As most Diesels have recirculating fuel systems, the diesel is continuously passed through the L500 De-Bug Unit to destroy microbial contaminants in the fuel tank systematically. Your filters remain virtually clear of slime, and the engine will retain operating efficiencies longer over service cycles. All of these benefits are permanently achieved without using any biocide chemicals. Provided the unit is fitted correctly and used, the L500 De-Bug Unit is guaranteed to reduce microbial contamination significantly.

The L500 De-Bug Unit is unconditionally guaranteed against manufacturing defects for 12 months.
