Hi Guys. Just wondering where the fuel filter is on my 2004 clk 320. Have a new one ready to go on and hopefully solve my rough running problems. Thanks
It's in front of the rear axle on drivers side.
There's a plastic tray covering filter and pump.
If you haven't replaced fuel filter for many years you will definitely notice an increase in fuel consumption.
Don't forget to replace all perished vacuum hoses around intake otherwise your car could run very lean.
Good thing is to also replace spark plugs
