On the subject, this noise is quite loud with my car. I was actually pretty concerned and disappointed by it until I learned that this is just the way it is with this car.
If I have the radio off I can just sort of hear it at a stoplight. Where I really notice it is when I go to drivethroughs or driveups and it sort of echoes off the walls.

If you're referring to your previous GS 430, it didn't have a direct injection engine and the 3GR-FSE engine that was in your 06 GS 300 was always quieter than the newer 2GR-FSE engines used in the current IS 350, GS 350 and your GS 450h. That's probably why you never really got to hear the ticking noise. My 07 GS 350 isn't too too bad but I can certainly hear it at slower speed, especially after cold start..

Well, since i haven't heard back from the poster about the fuel pump cover. I decided to call my Local Lexus parts Dept and inquire about it. They were able to give me 2 part numbers. There will be a total of 2 covers that will basically clam shell over our fuel pump. The price for each one is $12.77. It seems like a reasonable price to try, since the heat wrap will cost about $20 ..haha 
Here are the part numbers ( #12606-38010 & 12605-38010). They even sent me a PDF of the LS fuel pump cover. One thing I'm confused is that the PDF shows 2 fuel pump on both sides of the engine. Anyone know anything about this? Attach is a the PDF.
If i don't hear back from 5000670 soon, i might just go ahead and buy it and give it a try.
BTW BinaryJay- Get a life and get out of your mom's basement for once. Always complaining about every damn post

I think this part is standard on our cars as well, guys. If you look at the parts diagram for the 3GS, it shows this part same as for the LS. Same part number even.

This time i notice the diagram showing a fuel pump without covers. Does this mean that from 2008-up, no covers were installed?? humm..

After some complaining, my wife was able to get Lexus service to install above stated covers. In our opinion, it might have helped about 10 to 15%. She is still not happy....ARGH

Sorry for the wait! I see that someone already went to dealer and got the part #. The numbers are right and that there are two pumps on the LS460. The part number that you will need is 12605-38010 and it is for the right side pump (passenger side). The GS300 and 350 have only one and thats located on the right side.

Alright Guys.
Just wanted to give an update on my experiment. I ordered the covers for my GS 350 and installed them. Installation was easy, just had to remove the intake hose going into the throttle body. I do notice a slight decrease in noise, but not much. I agree with Leonsup, its about 10-15%. So, if you're expecting a big decrease in noise, then this isl not what you're looking for. Overall, for $27, i think its worth the investment. It reduced the noise enough that i can barely hear the ticking noise inside my cabin. Here are some pics. Enjoy

so you guys are hearing the ticking noise, inside the cabin, with the windows up, while driving down the road?

No..While driving, my car is smooth and quite. It's when we're at a complete stop with the engine at idle, that's when I would hear it inside my cabin.
