Fuel Rail Leak?? Yamaha F225

General Boats and Motors

I recently changed the oil and fuel filters on my motors and went to fire them up. Both started immediately and ran perfect. However, I noticed the left motor was leaking clear fluid which turned out to be fuel. It was a fairly significant leak. I figured I hadn’t completely seated the fuel filter bowl but upon closer inspection discovered the fuel was coming from high up on the starboard side of the motor. Without pulling anything off it appears to be coming from the fuel rail on that side. The motors haven’t been run hard in about 4 months although I cranked them in the driveway every few weeks.

I’m hoping/guessing it’s just a fuel injector o-ring or something simple like that. Maybe the fact it’s been sitting for a while has made them brittle? Anyone else had a similar problem? Anywhere else I should be looking? Thanks

Possibly a hairline split in a fuel line from catching it with the cowling?

Last year I pulled my fuel injectors out of the F150 (there were 4) and sent them to be cleaned. Each injector has 1 or 2 rubber o-rings where they connect to the fuel rail. The o-rings seemed to be very durable. Possibly one of them isn’t seated correctly?

I’d try to identify exactly where the leak is coming from before taking the injectors out.
