Veloci's Pre-Heated filter is specific to the Blaze 100, Blaze 200, Blaze 300 Firesorm400HC and Fire 155 in size and installation. By pre-heating the fuel in cold temperatures, you will optimize the spray pattern of the fuel for complete atomization. This will reduce buildup of unconsumed fuel that is commonly found during the winter months as diesel gets cold and can gel.

Pre-heated Filter is already Installed on: -Blaze 200 -Blaze 300 -Firestorm400HC
