Mercedes Clk 430 howl near fuel pump

[@MrMarco6900]

Problem turned out to be the fuel filter. The canister without the blue tape. Changed it out and the howl disappeared.

Thanks, i have same problem with my clk 200. I will change it out as well.

Did you had a leak, because mine is leaking but I don’t know if it is fuel pump or a hose?

I guess its easier to replace a plugged up a pump filter than 8 injectors filters, right? 👍
