[C320-list] Engine/Fuel Issue with my 2001 Yanmar

[hcreech at comcast.net]

OK, I am out of town until the weekend, but am going to the boat Saturday to finish up winterization. I will take a picture of the clamped fuel return lines and send them to you. I don't know if it was you that posted the original request, but sounded exactly like the problem I had. Even the mechanics explanation was identical. Air infiltration caused by the fuel return line.

Herb, 

I would like to see a photo. I do not have this problem but I do keep a file of interesting issues (this qualifies) for future use. 

Thanks,

When my boat was new in 99' I had the exact same problem and the diesel mechanic told me that this version of Yanmar had a new pollution control fuel return that caused the problem mentioned. I have seen the much more involved solution with bolts and check valves. The solution he came up with is simply clamping off the fuel return hose, this hose caused the air infiltration. A simple brake clamp, less that $20 solved the problem, have been happily running for 12 years. I offered to send a picture of the simple fix, but no request.
