Changing the fuel filter is a pain because the large feed hose has to be clamped but there will still be a little bit of fuel escape all over your arm. There should also be a screen in the tank itself which can block up. There should be small screens within the fuel system itself (there are on the K-jetronic) that can block up. Far as the oil goes, if you give the filter a chance to drain there should not be oil come out of it but change the filter reguarly because they are fairly small for the size of the motor and I know the earlier cannister types (in the M102) where quite inadequate. Also if you plan on keeping the car for a while get the best filters available, that is not an area to save money.

The fuel filter is probably under the rear of the car, by the right
rear tire, behind a plastic panel. At least that's where the fuel
pumps and filter are hidden on all 124 gassers. The M103 oil filter is
awful, it's a spin-on at the rear of the engine. Removing the air
filter allows better access. It's mounted upside down, so when you
remove it, you'll get a half-pint of oil spilled down the block,
making a nice mess... every time. I much prefer the diesel, and M119
(V8) gas, cartridge filters which can be changed with zero spillage.
If you think the diesel oil fiter change is a pain, you'll looove the
M103, heh-heh. Stick with the OEM filters from Rusty, of course, or
perhaps the K&N (my favorite non-OEM spin-on oil filter.)

Subject: [MBZ] Maintenance items on 126 -- M103

I will be flying out to Tampa this Friday for my Rendezvous with my new
car.  The seller is meeting me at the airport. He will have title in
hand and I will have check to present to him.  Here's is my question.
Where is the fuel filter on a M103?  Is it as easy to change as on the
diesels - i.e. spin on?  The spark plugs are probably fairly accessible
given the fact that it is a straight six.  Any weird maintenance quirks
I need to know about the M103 or the 126?  Things like coolant flushes,
power steering fluid changes, transmission fluid changes, and brakes
will be fairly standard, so I won't have to (get to) learn anything new
about that.   I just thought about it, I have no idea where the oil
filter is? Is it as much of a pain as on the 123/124 diesels?   Any
thoughts would be great?
