920 ProXP fuel tank vent/breather

[Jimmy Lee]

Hey all, I am trying to diagnose an issue I am having. I am having some power loss that progressively gets worse as the day goes on. Someone told me to check the fuel tank vent. Is there some type of vent on top of the fuel tank? Any help would be very appreciated!

Yes there is a vent. Open up the fuel fill cap and look to the right of the filler hole and there should be a little hole that is the vent. Sometimes the vent hose has a low spot and fills with gas not allowing the air to enter. If the problem gets worse as the day goes on I would doubt that the vent is the issue. Recently I had an issue with performance and it was the hose from the bulb to the motor was bad.
