Greetings,

I don't own you year diesel but there should still be three filter on your car regardless of year. The first two should be under the hood almost next to each other, one a spin on design fuel filter, one that is clear or opague in color which strains the garbage from the tank and one screwed into the fuel tank exit that is the tank filter. The first two should be on the drivers side of the vehicle, follow fuel lines to locate and the one in the tank is right above where the fuel line comes out of the tank.

I can't swear to it in a 124 chassis, but on a 606 engine in a 210 chassis, it's a little different than Charles described. You should be able to find the main filter, it's on the drivers side of the engine, high up and on the front. It hangs underneath a housing, looks a little like an oil filter. You'll see the head of a bolt on top of the housing that holds the filter in place.
If you look at that bolt head, then look more towards the engine itself, you should see a black disc being held down by a 'Y" shaped bracket with a smaller bolt. That's actually the pre-filter on this engine. Just remove the bolt and bracket and pull it out.
One trick about the pre-filter is that the prefilter needs a new o-ring to seal it, and it hasn't been included in the prefilter box lately, so be sure to get a new o-ring and put it on the new prefilter before installing it, or the engine won't run long, the filters will fill up with air due to the missing o-ring.

ps when installing the new main filter, I recommend filling it with Diesel fuel prior to installing it.

I'm more interested in the rear fuel filter than the front two. I did locate the filters and the pre filter is more like a screen than an actual filter. I will get under the car and look for the tank filter. Thanks for your help.

Tom:
To the best of my knowledge, there isn't a filter back there. You have the main filter and prefilter up front. There is probably a strainer of some sort in the bottom of the fuel tank inside the tank, which isn't normally something you'd need or want to service.
