I didn't need to replace mine yet and so I don't know where it is on the Clk500. But I did replaced one on my Clk430 and it on the rear passenger side above the suspension. You won't see the fuel filter until you remove the black plastic cover. So it might be hidden on the Clk500 or it might be in the gas tank. Dyno would be able to help you with a pic diagram.

W209s are similar to W203s, I'm not 100% sure it's the same procedure but here is the W203 thread:

That's a 4 cylinders. How can it be similar with the V8? I think it in the tank because the Clk500 engine has the "returnless" fuel system.

Ok...i googled it and got a picture of the fuel filter. Definitely 100% is in the gas tank based on the pic. If it were a cansiter, then it would be mount inline like on the Clk 430.

You pretty much have to remove the rear seat for access to the fuel tank pump.

Do you mean never replaced?

My guess is it is big enough that they don't plan on it ever being replaced.

OTOH I had a 68 Ford that all it had for a filter was a screen right before the carb. I guess they though anything smaller was going through the engine. The mechanic pun an aftermarket in line filter in it after he cleaned out the screen (which was starving the engine for gas).

You really think they went into the tank and didn't find one? That part looked a little integrated and necessary to be just flat left off.

I've seen used cars that have had them removed and not replaced but I'd be shocked if a factory actually forgot to put on on. Stranger things have happened though.

2003 CLK500
So.... has anyone tried replacing fuel filter?
I hit 60k and I am supposed to get it replaced, but it costs a lotta money due to long hours of labor so my mechanic said screw it for now and told me to come back when I have money.



Who actually got this thing replaced and how much did it cost?
And, has anyone not get this replaced ? I'd like to know what would happen if I don't get this replaced for another 3 years. Btw.... I have 2003 CLK500.
I think the fuel filter filters bad particles from gasoline you put at a gas station.
I put Chevron Fuel System Cleaner everytime I get engine oil changed (every 5k miles). I hope this is enough that I don't have to get the fuel filter replaced.



For those who are curious where it is located, I got a picture of fuel filter from parts.com



1) Fuel tank Clk320 clk500
2) Mount strap Mount strap Either Side
3) Cover
4) Filler neck Coupe
5) Grommet Coupe
6) Hose Coupe
7) Breather tube
8) Filler cap
9) Filler cap Seal
10) Sending unit Clk320 clk500
11) Fuel filter

Older models have the filter outboard at the rear of the tank. late 2005 onwards NON AMG cars started placing it in the one fuel level sensor in the tank. Fuel sensors & pump are under 2 round plates under the rear seat. AMG vehicles had it in the tank earlier. In tank units require replacement less often due to capacity.
