Hello everyone.
I recently purchased a beautiful 2007 IS250 with 127K on the clock.

The fuel lines going from the front of the engine to the fuel pump are rattling and making a lot of noise inside the vehicle. Mainly below the rear seats and floor board.
The noise is the loudest between 2000-3500 rpm. Under the car I have touched and moved the fuel lines a bit in hopes to see if the noise could be reduced by shifting the lines. Not much success.
I felt the fuel line where it connects to the Fuel pump. Seems like there is a lot of vibration shooting through the lines.

Has anyone here experienced this Noise?

I only found one thread on the same issue. But issue was never resolved.
I drove 6 IS250s in the last month and not one sounds like this on the inside.

Any any Help would be greatly appreciated.

Replace the faulty clips around where the noises are.

I double checked the clips, however, they look intact and not worn. Vibrations in the lines are the most evident from where the fuel pump line starts to just before mid way under the car.
Could the fuel pump be creating a vibration in the line and thus making the line rattle?
