One of the most crucial components of an outboard engine is the fuel filter connected to a cut in the gas line. A significant number of boat owners are unaware that the filter exists and, therefore, do not realize it requires servicing. Unfortunately, both land and water-based gas stations inadvertently sell gasoline and diesel that contain water. Outboard motors do not function well when the gas is watered or contains contaminants. Understand what an outboard inline fuel filter does. 

What Does An Outboard Fuel Filter Do

Fuel filters remove small particles and water before the fuel enters the engine. Marine engines consist of small parts that are easily clogged. Additionally, the filter removes water to prevent the engine from functioning poorly and assisting in avoid internal corrosion.

Avoid waiting until the engine runs rough due to lack of fuel flow from a clogged filter; however, this is a sure sign it requires replacing. 

Inline fuel filters are clear to which allows for frequent inspections. Fuel filters with debris have turned black, or water requires replacement to optimize performance. 

How Full Should An Inline Fuel Filter Be

When a fuel filter is partially filled, this indicates a blockage in the gas line or a clogged filter that requires replacement.

How Do You Change An Inline Fuel Filter

The process of changing the filter is simple; however, take precautions. Whenever you are working with gasoline, the risk of fire is always present. Avoid working on the engine when it is hot and shut off the gas.

Once the gas line is closed and the engine is cool, begin replacing the filter. A filter is installed on the gas line and is secured with zip ties. Cut the zip ties on the top and bottom of the filter without damaging the fuel line itself.

Once the zip ties are cut, take note of the arrow indicating the flow direction and pull the filter free from both ends. Gasoline will likely spill; therefore, clean the spill with a rag. 

Remove the new filter from the box and pay close attention to the arrow. Correctly line up the filter and place the hoses on each end. Replace the zip ties to avoid the fuel lines from coming free. Snip the excess zip tie. 

Always remember to turn the fuel from off to on. Lastly, test to ensure that the motor is operating correctly before heading out on the water.
