Transparent Inline Fuel Filter for 7 mm Hose (Gasoline/Diesel)

This transparent inline fuel filter for 7 mm hoses is an essential component for maintaining small and medium marine engines. It installs easily in-line on your fuel hose and immediately begins trapping impurities from the fuel. Dirt, rust, or sediment that finds its way into gasoline or diesel can clog carburetors or injectors and cause loss of power. By using this filter, fuel is purified before reaching the engine, helping ensure smoother performance and longer engine life. The clear housing lets you monitor your fuel’s condition at a glance – you can quickly see if debris or water has collected in the filter and know when it’s time for a replacement. It’s advisable to check the filter regularly and replace it when it becomes dirty (this model is a non-cleanable, one-time use filter). With a standard 7 mm diameter, this filter integrates seamlessly into most portable tank fuel lines and engines. Simply splice it into the hose and secure with clamps – delivering clean fuel to your boat’s engine is now assured.

• Use Cases & Recommendations: The Ø7 mm fuel filter is especially useful for small boats, RIBs, and inflatables equipped with lower to mid-horsepower outboard motors. It fits standard fuel lines found on portable gasoline tanks, and can even be used on gasoline generators, lawn mowers, or other power equipment using ~7 mm fuel tubing. For optimal engine performance, we recommend replacing the filter at the start of each boating season or every 50 engine hours, whichever comes first. This practice ensures you’re always feeding your motor clean fuel and helps prevent unexpected engine stalling due to fuel contamination.
