gas and air leaks at hose connection to motor

[Joe Mueller]

I've a 2003 4 stroke electric start 15 hsp Yamaha that I've been having gas and air leak problems at the connection to the motor from the tank; I just bought a new gas connector for the motor from you and it still leaks. I also bought a new tank and hose. Is there a special hose connector to hook to the motor that I can buy for this motor? thanks

The Yamaha fuel quick-disconnect on the cowling should not leak unless the O-ring is damaged or missing? Each fuel line connection should have a hose clamp to keep it tight. Your fuel line should be Marine Specific, and not automotive type, and it must be the correct diameter for your fittings. Good Luck!
