FloTool, by Hopkins Manufacturing, offers the most comprehensive and highest quality offering of fluid handling products. Driven by innovative, no-mess product solutions, whether youre changing your oil, topping off the antifreeze or checking all your automotive fluid levels, FloTool has the right application. FloTool's Small Non-Conductive Portable Fuel Filter keeps your engines running better and lasting longer. It's vertical filter design allows gasoline, diesel, heating oil and kerosene to pass through while preventing free standing water, dirt and debris from getting into your engine. This is a must, as these contaminants, especially water, can plug filters, corrode components, decrease efficient combustion and cause engine shutdown or system failure. This small fuel filter is great for generators, small lawn and garden equipment and powersport equipment.
