Our Onan 4000 generator has a random clicking/metallic sound at times. It seems to occur mostly during warmer temperatures. If it's happening, it doesn't change if the load/rpms on the genset change. Since it didn't change with engine load change I was thinking it was probably an odd rattle somewhere but I see a lot of references to the fuel pump on the web making a clicking sound.
Has anyone had this issue with their genset? Could it be the fuel pump making the sound even if it doesn't change based on load?
We have a trip planned in early August and leaving from Dallas I know we'll have some pretty high temps so I'd like so sort out any temperature related issues before we hit the road.
