After that experience I'd never concern myself with a little noise, especially a whine. Now if I could here it grinding itself up then I might be concerned.

With that said, mine was whining all season but did change up now and again and was more constant by then end. However, the bike never coughed even once. The problem is, it bugs me because it was never there before, and probably shouldn't be there now. I always wonder if I will eventually be left stranded somewhere. I'd much prefer the 103 K thing.

I'm honestly not worried about it. Sounds just like the pump on both of my sportbikes. Both of them sound like that, but you can't really hear it over the engines.

That's probably a good plan and I'll give it a shot when it's done snowing (more today dammmmit). I'm not familiar with Marvels, but I already have some (but never used) SeaFoam. Same thing but different brand???

Seafoam is more of a solvent. Marvel's is an oil.

Both seafoam and marvel mystery oil are combustibles useable directly into the fuel tank.

I have many customers that still use Marvel religiously, and claim its upper cylinder lubricant is the reason their industrial diesels run such high hours. I can't deny, some of their generator engines have gone 30,000 hours, when I typically overhaul them at 15-20K

Thank you guys. I got he Seafoam because it sounds to be fairly popular. But like I said, I haven't used it yet. I hadn't heard of Marvel until now. It's nice to learn something learn something new.

Fuel pumps have their own personality. Some are bigger whinners than others like people. I don't pay much attention to them. You will know when there is a problem like how the engine runs or doesn't start.
