There is a plastic tab that sticks out from a sort of “barrel” on the
actuator that goes into the grommet or whatever you want to call the part
that projects through the fuel door all and provides the locking bit.  If
you push down on the tab and pull back the actuator comes loose from the
grommet thingy.

Anyway, having done this I found that for whatever reason the metal pin
that does the locking of the fuel door from the actuator wouldn’t move,
like it was frozen in the actuator body.  The actuator is sort of a weird
setup unlike the typical vacuum actuator, since this pin is attached to 
the

diaphragm and is moved by it moving back and forth to provide locking and
unlocking.  Since the pin is on both sides of the diaphragm, it has to be
sealed to the actuator body or vacuum/pressure would leak out (remember
that W126 central locking uses pressure AND vacuum.)

The seal that the pin goes through was stuck fast to the pin.  It took
some goomph but I got it loose without damage and once having done so I 
put

some dish soap on the pin and moved it in and out of the bore so the seal
would get lubed up.  After I was satisfied that it was moving freely I
reassembled the actuator halves and hooked it up.  Voilá!  Working fuel
door lock now.

The only thing I can figure is that the car sat for extended periods of
time, and the seal in the actuator housing just got old or sticky from 
lack

of use and the climate.  Now that I’ve freed it up hopefully it will
continue to work.

I love those cheap/free repairs…

[Dan--- via Mercedes]

Thanks, but I'm good. I found the service procedure for R and it say little 
more than "release the tab."

I just have to shove my arm back up in there and start poking around until it 
comes off or I break something

[MG via Mercedes]

Yeah, that's what I see in the manual. It's just a line drawing. 
I can send it to you if you don't have it. My best guess is to 
push the tab toward the front of the car and push the vac pod 
toward the right side of the car. Thats if the orientation in the 
picture is the same as in life. The picture is in the correct 
orientation for the earlier models as if you are looking at it 
from the back where you are working.

Re: [MBZ] Release Fuel Door Actuator?

[Dan Penoff via Mercedes]

That’s not what I’m asking.  I’m asking how to disconnect the actuator from the 
part that projects through the hole in the side of the fuel filler area so the 
actuator can be removed from the car.

Different chassis, but on my 124 sedan, behind the trunk liner, there is a 
yellow round knob on the top of the shaft on the top of the actuator.  Pull up

[MBZ] Release Fuel Door Actuator?

[Dan Penoff via Mercedes]

I’m trying to figure out how to disconnect the vacuum actuator on the fuel door 
on the 300SEL (W126).  You can’t see in there very well, and the business end 
of everything is in the opposite direction, too.

I know there’s a tab of some sort that you can push on to release the actuator 
from the bushing that goes through the opening to the fuel door, but without 
some sort of visualization I’m not having a lot of luck.

I’ve found a few pictures and references to this on the interwebs, but none of 
them are terribly detailed or have a good picture.
