Fuel Pump Whine (update)

[redjay]

Hello All,

I posted a thread a few months ago about how the fuel pump on my 05 started to whine all of a sudden. That was about 7,000 kilometres ago. I have ridden all summer with it with no issues however it appears to have got louder recently so I am contemplating replacing it. It is very expensive, $400 in the U.S or $665 + taxes Canadian at the Kawi dealer here in Ontario.

Today I took the pump unit out of the tank and had a look at it.
It has quite a few parts to it that you can remove but the motor is a sealed unit. There is a filter that you can remove and clean. It looks like a tea bag. Mine was not dirty. I was hoping it was that that was plugged and causing the pump to work harder to compensate. The unit is made by Mitsubishi.

I put everything back together but did not see anything that would be causing the whine in the parts that I could dissassemble. I am going to put it back in the tank this week and try it before I order a new pump. I will keep you informed.
