DIY: 2000 C230 Kompressor Fuel Filter Replacement

Replacing the Fuel Filter on this MB is very easy.
Put the Car on 3-Ton Jackstands for Personal Safety.

Location of the Fuel Filter is Right, Rear.
Between the Drive Shaft and Rear Tire.
It’s covered by a Black, Plastic Cover Guard.

Remove 3 Screws holding this Shield up
The Fuel Filter is quite large and is held in place
By a Metal Bracket and the Hoses are Clamped
Onto the Fuel Filter ( in the Factory ) with
“ Permanent “ Crimp-style Clamps.
I replace these annoying Crimp Clamps with small
Worm-screw Clamps ( see photo )

Remove the Phillips Screw holding the Fuel Filter
In your case you will have to excise the crimp clamps off.
Once removed they cannot be reused.

*** WARNING:- Your Fuel Filter is PRESSURIZED. :eek:
Be ready when you remove the Fuel line for Gasoline
To start dripping.

*** NOTE: Understand that Fuel flows FROM the Gasoline Tank,
Through the Fuel Lines and TO the Engine. Knowing this you MUST
Ensure your Fuel Filter is put on correctly. there is an Arrow on the
Fuel Filter indicating : →→ Fuel Flow. :cool:


If all this is too much for you ( I understand it can be intimidating )
Then BEFORE you remove the Fuel Filter, note the writing on the
Fuel Filter, align the New FF alongside it and match it. Labels
Forward, writing clearly read.

Carefully remove the Old Fuel Filter
Pull off ONE of the Fuel Lines.
Immediately Keep your Fuel Line in a Vertical position.
This will minimize Fuel loss.
Install your New, Small worm-Clamp
Input the Fuel Line into the New Fuel Filter
Tighten the Clamp
Take the New Fuel Filter and push it through the old Bracket LOOSELY
Remove the SECOND Fuel Line, like you did the first one.
Remove old crimp Clamp, wiggle the Fuel Line off, keep it Vertical
Quickly install the new mini-clamp
Push the Rubber Fuel Line onto the New Fuel Filter
*** Make sure the Rubber Lines are pushed hard against the
Fuel Filter “wall”.
Twist your Clamp so you can tighten the Clamp down
Make it look neat and presentable.
Once your satisfied, then tighten the Fuel Filter Clamp onto
The Body ( the main clamp dead center on the FF-See Photo )

Reinstall your Black, Plastic Guard.
Update your Maintenance Log Book to Indicate Mileage/Date
Fuel Filter needs replacement every 10,000 --- 15,000 Miles.

That’s about all. Estimated Time: 15-25 Minutes.

How much fuel drips on this procedure? Are you doing the replacement while gas is dripping?

I would assume that once the pressure gives and after the initial spurt there should not be more gas in the line until the pump is activated again. Trying to make a mental picture of the procedure as I may need to change my filter soon.

Be safe, and save yourself a Gas Shower...

Use Hose Clamps...

Where do you get these?

It seems they are easier to use than worm gear clamp where you need a screwdriver.
These shown are "Stahlwille" brand, and run $26 bucks for a set of TWO. Samstagsales.com

You can also get good German quality (Wiha) at your local MB dealer. I recently purchased two for $20. Part# 000 589 40 37 00

The next lower level are the "Pep Boys" type places, where they will run around $8 for the set of two. In years-gone-by I used to use the cheap-o ones (like Lisle?), which don't work quite as well at sealing the line as the German types, but it's better than taking it in the face.

Either way, ALWAYS use eye protection and wear Nitrile gloves.

Please Help! Can you tell me where the fuel pump is on the 2000 C230 Kompessor? Also maybe a procedur how to replace it.
It's under the car, towards the back. There's a black plastic housing around it and the fuel filter. You'll need to remove the hex screws and take the housing off to get to the pump.

How do you know it needs to be replaced anyways?

Carhas 177k miles on it.

I had a friend analyze it. Came back with
P0171 Self Adaptation at Limit
P1163 Oil Level Sensor
P0243 A/F Switch over Actuator
P0300 Misfire (assume #3)
P0301 #1
P0304 #4
P0302 #2

Took it to him when car wouldn't run or idle as if out of gas. Read where when it goes it goes quik.

Fuel pump replacement

DIY Tip - a pair of small G-clamps will work well for clamping the fuel lines. Just make sure they have no burred edges to pierce the hose, and tighten til you feel it 'bottom out'. Left no scuff marks on mine. Also note that the filter probably holds more fuel than you imagine. When I first started up after, the pump 'priming' sound was much fainter, like a hum rather than a whine, and after 10sec of idling, I heard a brief gurgling sound...? is this tearing of the filter due to lack of priming before installation? Is that necessary, even though I primed it via the pump by having the key 'on' for 3 x 5sec lots...

when i did mine i had just driven the car a few minutes before removing the fliter, so the pressure was still high. i had not "shot" of fuel come out at all. just a trickle of maybe a total of 1/4, probably not even that much. it was VERY easy to change in less than 10 minutes. i did not clamp the hose or anything , it only takes a few second to pull off the clips and change the filter.
