A boat with clogged fuel lines is hard to miss because it will develop performance issues on different scales. Although fuel line issues do not occur frequently, it is essential to understand how to handle the situation and return normal operations safely.
You could get professional help but if this is not an option, the tips I reveal below on how to clear a clogged fuel line will come in handy.
Signs of a clogged fuel line
When the lines are clogged, issues such as trouble starting your boat emerge. The engine also tends to fail when you least expect it. Depending on the level of blockage, you might experience issues when running on full throttle or feel the engine struggling to pick up speed.
Why are the fuel lines clogged?
A common reason behind clogged fuel lines is old age. Fuel lines wear out eventually causing the weaker interior layers to collapse and obstruct the quantity of fuel delivered to the engine. Check the condition of the fuel lines first and replace them if worn out to see if the engine trouble ceases.
Besides, look at the fuel filter. A worn-out or unclean fuel filter fails to trap unwanted particles from circulating in the engine. It is best to replace the filter if completely worn out or wash it to remove the build-up.
The quality of fuel used can affect the performance of your fuel lines over time. High-quality fuel has less sediment; therefore, purchase fuel from reputable sources only.
If your fuel tank is a bit rusty, rust is expected to build up in the fuel lines over time. A rusty fuel tank together with high condensation in the tank will slowly clog your fuel lines no matter the times you replace them. Check on the condition of your fuel tank to eradicate the same problems in the future.
Tips on how to clear a clogged fuel line
Dealing with engine issues can be frustrating especially if you have no clue of what to do. The easiest way to unclog a fuel line is by using compressed air. You do this by forcing air through one end of the fuel line and letting the other end rest inside a container or on a piece of cloth. The air pressure has to be high to force out any rigid obstructions. You can do this using a vacuum, air pump, or blower.
Alternatively, disconnect the fuel lines and attach them to a separate fuel pump with a good filter. As you run fuel through the air pump continually, the filter will get rid of any sediments clogging the pipes.
Another method would be using an aerosol injected cleaner. The cleaner will infiltrate the fuel lines and dissolve rust and other unwanted particles in the system with little effort. Ensure to detach the fuel lines and inject the aerosol continually until the liquid coming out of the other end is clear.
