Suzuki DF2.5 leaking fuel tap

It sounds ethanol related. These were made before the increase in ethanol was proposed, so the fuel lines are not resistant to it. The hose, tap and filter are likely to be affected and should be replaced with E10 compatible components.

Also affected is the needle valve in the carb. There may be an E10 replacement available, but the best preventative is to make sure the carb is emptied of fuel when you're not using it. Usually by turning the fuel off and letting the engine stall.

I don't think this engine has ever been run on E10 fuel.

Sorry don't know it was just one I had from another engine. Have look at parts diagram on one of the yam sites or go to a yam dealer. Basically the same device, just different design and better.

Did you fit this without modifying the cowling? The fuel tap for the DF2.5 has a long stem that goes through a slot in the cowl. I don't see how an alternative would be made to fit without cutting the cover somehow. Perhaps you could provide some photos. Cheers.

Can you send some more photos? Maybe I can say something

Make a gasket out of gasket paper identical to the rubber seal . Place the gasket in the tap body underneath the rubber seal. That usually fixes it
