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

[Bruce]

Generally the only way that fuel can leak back is if air leaks in.  I'd  
check all of the fittings and make sure they are tight and not leaking. I'd  
also check your filter to make sure it is not blocked or lose.

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

All,

I am hoping that someone has had a similar experience and can provide me  
with some guidance. As of late I have been having an issue with my engine  
(Yanmar - for my 2001).

When the issue began 3 weeks ago,  the engine started fine, ran for about 3  
minutes, than sputtered and would not restart. When it stopped it  
sounded/behaved like a lawnmower running out of fuel. 

My mechanic said it had to be "primed", which he did, and it ran fine for  
ablut 30 minutes until he shut it off, and let it sit over night. The next  
morning, the same thing happened, it ran for a few minutes and sputtered  
out.

He now tells me that he suspects fuel is draining back to tank through the  
fuel sytem and he is going to "install a check valve" into the system. that  
will "hold fuel in system". Please note that half of my current fuel is new  
this year, purchased very early in the season.

Has anyone ever had a similar experience and does the mechanic's solution  
seem logical?

I would appreciate any thoughts! 

Thanks,
Tom Dames
