De-Bug Clean Fuel Units

L1000 De-Bug Unit

To Eliminate Microbial Contamination
From Diesel And All Hydrocarbons.

Microbial Contamination Or HUM - Hydrocarbon Utilising Microorganisms, being Bacteria, yeast, and fungus that colonise and eat the energy from diesel, creating slime that blocks filters and injectors and sends fuel acidic, causing corrosion within all of the fuel system.

Microbial contamination is difficult to eliminate. Additives have some success, however when the bugs are poisoned they create sludge that accumulates in the bottom of fuel tank/s that will later be sucked up and block filters.

De-Bug Clean Fuel Units continuously eliminate microbial contamination while the engine is being used to supply bug-free fuel:
1/ Filters and injectors remain clear of microbial slime,
2/ Fuel returns to normal ph,
3/ Easier starting,
4/ Power and torque return,
5/ Smoother running,
6/ Lower fuel consumption,
7/ Reduce exhaust smoke.

De-Bug Clean Fuel Units are thoroughly tested in ILAC Accredited Laboratories and endorsed by genuine users.

35 years of production, no chemicals, no filters, does not create bug sludge.

Environmentally friendly; no poisons, reduce filter use to expected life, no wasted sludge filled fuel, reduced fuel burn and reduced black smoke.

Fit Once, then ongoing 'cost free' treatment for 12 years.
