Suzuki DF 140 noise

parm · 10 September 2009, 21:46

When i turn the ignition on on my suzuki df 140 there is for about 10 seconds a suction noise from under the hood from the right hand side if you are standing at the back of the boat looking forward. I have never noticed this before. Any ideas what it may be?

I guess its the fuelpump.

If it's injected, it's probably the high pressure fuel pump jamming gas into the rail.

10 seconds sounds like a very long time to prime a fuel system...it may still be the fuel pump priming but if it is I'd be starting to think/ask about why it might be taking so long.

Most probably the fuel pump, but I know on some of the Suzukis the vanes or valves somewhere also reset themselves depending on temperature and manifold pressure ready for a start up.
