Diesel Purge is one of the best products you can use to keep your diesel injectors and pump clean . Running a can of Diesel Purge through your engine (via the fuel filter hoses, it does not go in the tank) will result in a noticeably quieter and smoother engine.
Due to its flammable nature, Diesel Purge can only be shipped by ground service and cannot be exported.
Hose (below) is for use only in rotary pump and Pumpe Deuse TDIs. There is no simple way to tap into the fuel delivery system on common rail ('09 and later) TDIs or other common rail diesels. Best use of Diesel Purge in those vehicles is to pre-fill the fuel canister when changing the fuel filter.
