Canal boat Fuel Polishing Services, filtration, Diesel Bug Treatments

Fuel polishing for narrowboats is the removal of contaminants and water from diesel fuel and also can involve the cleaning of boat fuel tanks. Polishing has become necessary because since 2011 the fuel used by UK leisure boaters is the same low sulphur fuel (FAME) used in diesel road vehicles which contains a small percentage of bio-fuel which makes it more susceptible to microbiotic growth than red diesel.
Leisure boaters in particular may suffer when their intermittent activity allows water to collect in the bottom of the boat fuel tank which encourages the growth at the bio-fuel interface of microbes, yeasts and moulds. Collectively known as ‘Diesel Bug’ this can clog fuel lines and filters.


  • Untreated contamination will eventually get into the fuel system and block water traps, filters and eventually pipes and pumps. See our advice page about Canal Diesel Fuels .
  • Specialist Fuel Polishing firms, boatyards and marinas now offer fuel polishing and fuel tank cleaning using purpose designed equipment.
  • Many canal boats now include fuel purifiers or filters in their fuel systems to prevent the continuing build up of water and contaminants and there are a number of de-emulsifier and biocide treatments on the market which boaters can use to separate fuel and water and to kill the bugs in their own fuel.
  • Fuel filters should be regularly inspected to spot build up of contaminants, and fuel tanks should have bottom taps to allow water to be drained off regularly.
