Just purchased a 2014 rx350. I have had it only 2 weeks now. I can hear the fuel pump running even hours after it was parked and shut down. I un-screwed the gas filler cap, loud sound of air rushing in,then the fuel pump stopped running.
Is this normal for this car or is there something wrong with fuel system or filler cap?
Thanks, new to clublexus

This is normal. Do not worry about it. Freaked me out the first time also. It is not the fuel pump. It is the vacuum pump in the fuel tank.

Thanks to all. I found 3 lines of info in owners manual! It had me guessing
