Review on Premium Electric Fuel CLK320 CLK430 by Shalom Germann

Practically out of the box the pump was not good. It took me too long to get there so the return window is closed. The pump worked normally every 10 seconds. then there were breaks. If you've rocked or tapped the pump, you may hear it turn on and off, or even stop. Spend the extra money on a quality part and you'll be a lot happier. Replaced this POS with a quality German part and the car was fine as DO NOT BUY!
