Fitch fuel catalyst Parts & Accessories

Fitch Fuel Catalyst is a permanent in-tank device using a metallic alloy that reforms fuel at the molecular level — improving combustion efficiency, reducing carbon buildup, and extending engine life without any chemicals to replenish. Drop it in the tank once; warranted for 250,000 miles.

Also eliminates the need for fuel stabiliser during winter storage, keeping fuel fresh until spring. For Harley owners who store seasonally and want ongoing combustion improvement from a single installation, it's a straightforward proposition.
