Suzuki DF50 fuel vapor separator leaking
Posted: Sat Dec 29, 2012 6:05 am
this just started happening suddenly, for no apparent reason. I can only assume that something in the motor got knocked out of whack during the last drive to the ramp. There were some big bumps, so it doesn't suprise me. But now I need to fix it.
What happens is the engine starts OK, but fuel immediately starts gushing out of the flywheel cover and dripping into the water. I determined that the fuel is coming from the small hose that runs from the fuel vapor separator into a chamber within the flywheel cover. The manual that I have calls this the fuel vapor evaporation hose, but doesn't give any detail beyond that.

I found that if I pinch off that hose completely, the engine continues to run just fine, and I was able to get out and back using this workaround. But I'm sure it's not recommended to block this line as a permanent fix. The reply to the above posting suggests that the float within the fuel vapor separator needs adjustment, but my manual doesn't explain how to adjust it. Does anyone have experience with this?

Well this is a little embarassing, but I didn't know I was supposed to wait until the buzzer stopped buzzing before starting the engine. When I started the engine the "right" way in the driveway today, no more fuel leakage! So I assume that by prematurely cranking the motor, I confused the fuel separator or regulator and it decided to reroute the gas into the evaporation hose. Seems that all is well now. One more lesson learned . . . .
