I have a 98 CLK 320....just wondering if there was a difference in the two brands? By any chance does anyone know which part MB uses? Thanks in advance!!

Both are fine.
As far as I know, M-B uses both of them.

Online price: bosch $30, Mann $50, Knecht $74+. I don't know why knecht is so expensive.
I use mann. In fact all other filter replacements are Mann.

BTW, I think (seen) the OE MB fuel filter may be bosch ....made in spain!!! The last mann fuel filter I used was made in Israel. Its a small world. go figure.

'Cause they've got the fancy tougher-to-pronounce name!

On my 430 the fuel filter is by the passenger side rear wheel. It has a plastic cover you need to remove to get to the filter. You can get to it by raising the right rear wheel....makes a little more room.

I just did a fuel filter change on my C-class, same chassis as your car.

BTW, I got a fuel filter from the Mercedes dealer and it was slightly larger than the previous OEM filter. Not important but don't be surprised.

Tools needed are a phillips head screw driver - to remove bracket surrounding fuel filter.

I cannot recall if it was a 8mm or 10mm socket with extension to remove plastic shield, there were two bolts and each has an access hole in the plastic shield.

Two hose clamping tools - to squeeze hoses closed to minimize leakage, or two vice clamps with rubber protection caps so you don't damage fuel lines.

Two new hose clamps - ( different from above ), their are two kind of clamps, I use aftermarket that screw to tighten.

Pliers or mechanics scissors to break old hose clamp off.

Proceed as follows; raise rear of car securely, ramps, jack stands, (NOT with emergency jack ONLY, or rolling garage jack ONLY)

Disconnect battery, open fuel cap.

Remove two bolts holding plastiic cover in place.

Remove fuel filter clamp with phillips screwdriver.

Screw or break off old hose clamps.

Carefully but forcefully; loosen, pull and twist old hoses a few cm off the old filter connection. You may want to wear rubber gloves to get a grip or delicately use a flat blade to push hose end away from filter.

Attach hose clamping tools a short distance up the hose length.

Disconnect hoses from both sides of old filter, expect fuel to drip. Notice direction arrow is pointing on old filter.

Insert the two new hose clamps onto hoses, and replace new filter with arrow facing correctly.

Redo in reverse everything you undid.

May find a slight variation on your car, but nothing the procedure above dosen't address.
