I have a 2003 clk430 and I need to purchase a fuel pump, there are prices from $60 to $270. Can anybody give me advice or a review to which pump might be better?

AutohausAZ has the Pierburg (OEM) pump for $199.00. I would also change the filter ($35.00) while you are down there. Are you sure the pump is the problem?

Yes.......well I think Im at the spot ( fuel pump) , because with the car in idle I can hear a buzz/rattle at the rear of the car.The car also needs to be hot and runing for a long time (unknown amount). So, I lifted it up with the car running and found the fuel hose buzzing as the fuel runs threw it .You can actually put your hand on the hose and feel the fuel "pulse" . I have already replaced the fuel filter and now it seems the logical thing would be the fuel pump. Once again the car has to be running for a long time also, the car does not run funny or have any other problems while this is happening.

how many miles on your car? If you have a bunch it can't hurt to change it before you end up on the side of the road with your thumb out.

It could also be the fuel pump insulation. If the blue sleeve isn't wrapped around the pump, you may hear noise.

The car has @ 90,000 miles! Also, i looked under the car and it doesnt have a "blue blanket" wrapped around it, but it is very secure as I have already replaced the fuel filter.
