Before each season, it’s important to have a clean snowmobile gas tank and carburetor to ensure your sled runs properly. It’s also worth checking if the snowmobile fuel lines and fuel pump are all functioning well.
The gas lines and carburetor can dry out when your snowmobile hasn’t been used in a while. You can spray carb cleaner or use a starter fluid to help draw gas through the fuel system. Another reason could be that the snowmobile fuel filter is clogged, and fuel can’t go through.
How do you test a snowmobile fuel pump?
To prevent any accidents or mishaps while you’re out in the snow, it’s important to perform maintenance on your snowmobile’s fuel system before using it. Always ensure the fuel pump is regularly tested since it determines how smoothly your snowmobile runs. Here are steps on how to test your snowmobile’s fuel pump:
1. Lift and remove the engine cover to show the fuel pump, engine and carburetor.
2. Remove the fuel tank tubing that connects the fuel tank and inlet. Then attached the vacuum gauge to the fuel tank inlet.
3. Start the engine and while it’s running, check the gauge to ensure the vacuum is reported.
4. Remove the tubing that is connected to the engine’s crankcase. Then check for a pulse coming from the hose.
5. Remove the line that is connected from the pump to the carburetor, then attach the gauge to this line. While the engine is running, make sure there’s pressure.
What are the symptoms of a faulty fuel pump?
With a faulty fuel line, your snowmobile won’t run since the fuel won’t get to the engine. A cranking engine that won’t start and losing power at high speed, climbing uphill or when you come to a full stop are signs that your fuel pump is failing, and it may need to be replaced.
