Preventing Clogged Fuel Lines in Jet Skis

A clogged fuel line quickly ends a day full of fun on the water, leading to poor engine performance or a complete shutdown. Preventing this common issue is vital for any personal watercraft (PWC) owner. Proper maintenance ensures reliability and extends your jet ski engine’s life. SBT is discussing how to prevent clogged fuel lines in jet skis so that you can avoid this pitfall in the middle of an adventure.

Use High-Quality, Fresh Fuel

The quality of the fuel you use can have a direct impact on your jet ski’s fuel system. Low-quality or old gasoline contains contaminants and water, which lead to clogs and engine damage. Always use fuel from reputable stations and avoid gasoline that has been sitting for extended periods.

Using a fuel stabilizer is another effective strategy, especially if you don’t use your jet ski that often. A stabilizer prevents fuel from breaking down and forming the gummy deposits that can obstruct fuel lines and injectors. Add the stabilizer to the tank according to the manufacturer’s instructions each time you refuel.

Inspect and Clean the Fuel Tank Regularly

Debris can accumulate in your fuel tank over time, eventually making its way into the fuel lines. You should make it a habit to inspect the inside of your fuel tank periodically for any signs of dirt, rust, or other contaminants.

If you do find debris, you must clean the tank thoroughly. This process typically involves draining the old fuel and using a safe, appropriate method to remove sediment. A clean tank is the first line of defense against blockages in the rest of the fuel system.

Replace the Fuel Filter as Recommended

The fuel filter is a critical component designed to trap dirt and water before they reach the engine. Over time, the filter becomes saturated and no longer does its job effectively. A clogged filter will restrict fuel flow and cause the engine to sputter or stall.

Consult your PWC owner’s manual for the recommended replacement interval for your fuel filter. Sticking to this schedule is a simple and inexpensive way to prevent major fuel system problems.

Check Fuel Lines for Wear and Tear

Your jet ski’s fuel lines are exposed to heat, vibration, and the elements, which cause them to degrade over time. Regularly inspect all fuel lines for signs of wear, such as:

• Cracks
• Brittleness
• Soft spots

If you notice damage, replace the affected lines immediately to prevent leaks and blockages. This proactive check also provides a good opportunity to inspect other related components, such as your jet ski engine electrical parts, for signs of corrosion or wear.

Perform Proper Winterization and Storage

Properly winterizing your PWC is critical for preventing fuel system issues during the off-season. When fuel sits in the tank and lines for months, it degrades and creates varnish that ends up clogging injectors and lines.

Before storing your jet ski, fill the tank about 90 percent full and add a quality fuel stabilizer. Run the engine for a few minutes to circulate the stabilized fuel throughout the entire system. This action ensures that the carburetor, injectors, and fuel lines are protected from varnish buildup, making for a smooth start to the next season.

Following these preventive jet ski maintenance steps will significantly reduce the risk of a clogged fuel line. Consistent care ensures your PWC remains a reliable source of enjoyment, rather than a source of frustration. A clean fuel system is the key to a healthy engine and worry-free time on the water.
