I have a 1995 s420 and I can't find the gas filters to change. The car skips and runs rough so I'm guessing the filters need changeing. The car has 150k miles on it . Thanks for any help you can give me.

Try benzautoparts.com ... they have 3 different brands listed on their website, or your local MB dealer will certainly have a fuel filter for a 1995 S420. The rough running engine could be the result of other things too. When was the last engine tune-up? Have the ignition wires ever been replaced?

If it's like my E320, the filter is immediately forward of the rear axle. There's a platic cover with four screws that needs to be removed to reveal the fuel pump and filter.

First find what part number you presently have on the filter in your car, then order that number. I had to deal with a return because the wrong filter was listed in the catalog.

As far as the skipping problem goes... see if you can read the codes using on-board diagnostics. Sometimes there are error codes without the check engine light ever coming on. This may give a clue to the problem.
