Fuelsep Fuel Conditioning Unit, 800HP & Up Gas or Diesel Inboards

The Fuelsep is a maintenance-free fuel treatment device that improves the combustion of diesel fuel so it burns more completely. It utilizes a metal catalyst to chemically change aromatic ring-shaped hydrocarbons found in fuels into aliphatic straight-chain forms which are easier to combust.

Improved combustion means less soot, lower exhaust temperature, and better fuel economy.
You'll see a marked reduction in the diesel exhaust soot commonly deposited on the back of your transom and cockpit area.

This easy-to-install, in-line unit uses NO magnets, and is designed for all diesel engines, gensets, gasoline inboards, and even high performance outboards. See the Fuelsep Installation Parts entry for additional parts needed for installation. See Related Products, below.
Depending on fuel batch and driving habits, you can typically expect an increase of 5% in fuel economy - a real savings at today's high fuel prices.
