The vacuum line itself often has a wrap around clip attached to the rubber hose fitting. This is very tight to avoid leaks. If you must take it off, be careful in doing so. Gently pry it open with pliers by squeezing the two pieces together then, slip off the fitting. If you merely want to test the locks to see if they function properly, simply push them down while the car is running (idling) or pull them up the same way. The cars locks do work many times even if the car has not been operating (idling) for a few days.
NOTE: On hot summer days, its not uncommon to have your locks not work when getting back INTO your car. A vapor lock happens causing severe pressure build up. You cannot unlock your car no matter how hard you try. To avoid this for any car, simply park your car physically in a shaded area or wait until the sun sets and return to your car..it will then open after it has cooled down.

Where is the button to open the fuel door on a 1983 Mercedes Benz 300 SD Diesel?
To my knowledge there is no button. There is a small recess at the back top edge that you slide your finger in and pull to open. Gently! If you get a clunk when you pull and the filler door stops, your vacuum operated lid lock is in the locked position. Unlock the car and try again. If the filler lid is locked with the car unlocked try started the car to 'charge' the vacuum system. If this does not work you will have to open the trunk to access the lock, and manually push the locking pin back.

Why wont my1987 Mercedes Benz trunk open?
All locks both interior and exterior are operated by a central vacuum pump system. All locks must be in working order, no leaky hoses and a working vacuum pump in order to open the trunk. Avoid locking your doors on very hot days when parked in the sun...it can and often will develop a vacuum air lock build up from high temperatures. Park in the shade or partly shaded areas to avoid this. If it has already happened, open the car when the sun has already set. It will open normally when the pressure has subsided in cooler weather.
