Hey Dave
Did you look in the trunk for the manual release?
It should be on the side with the fuel door,guessing drivers side behind the trunk interior trim.

I'm not too sure on these..
But I remember hearing something about the 'central locking system' and fuel door is released when door locks are unlocked?
Maybe I heard that wrong..just something that came to mind.

Tom.....I understand some of the central locking operation.The part that I don't get is the locking and unlocking of the car door to get the gas door to open... do you use the key or just by pulling up on the lock button? Since this is a vacuum operated system..does the car need to be running? I just know I'm overlooking something.

I really don't know these cars for squat but if it really is a vacuum motor system (I've had several) they work or should a few times more when engine is off with a vacuum storage ball somewhere. This may use a belt driven vacuum pump instead of the engine for source.
Does the thing have an owner's manual in it - I'd look. There probably is a separate way to open jus the gas tank door which wouldn't be in english but perhaps some diagram - near gauge or what I don't know. I do recall before remotes that all doors locked when you used the key to lock the car - perhaps that also opens the gas door - dunno??

I think that the vacuum pump is under the rear seat...

I've already replaced one on the engine that kinda runs off a cam-like drive....I wonder what other surprises are to be expected?
