07 600 cfi whining? fuel pump?

[ProXJC]

The last few rides on my wifes 07 600 cfi I have been hearing a whining noise. It seems to stay constent no matter rpm. Im thinking its coming fron the fuel pump area near the top of the gas tank. Is this a sign of a fuel pump starting to fail? Any input woulf be great.

I had an '08 600 that the fuel pump was noisy. You could hear it when the motor idled. It also began to bog anywhere above about 1/4 throttle. It turned out that the fuel pickup lines inside the tank were brittle and falling apart due to ethanol fuel. I replaced all the lines in the tank and the fuel filter to solve the problem. You could also power up the fuel pump using the 2 prong small white plug near the front shock tower on the left side to listen to the pump without the engine noise. When the pump starts having to work hard they get noisy.

Did the noise go away when u repaired the lines?

Yes, it quieted right down. The difference when powering up the fuel pump without the motor running was very apparent. If your lines inside the tank are intact, I would replace the fuel filter.
