I have a 1978 300d and was having problems with the door locks. So I recently had the vacuum hoses changed. The doors now lock and unlock well with the car running and once I turn it off, I can only lock and unlock the 4 doors once. I not only changed the hoses, I also changed both passenger and the rear drivers elements and the vacuum lock cylinder, as well as the trunk and fuel door elements. The vacuum chamber was also changed. I haven’t changed the gray vacuum hose or anything on the reserve tank. But the problem now is that I can’t get the fuel refill door open (with or without the car running). This in time will lead to another problem, no diesel. I am not sure what could be wrong. The vacuum pressure was checked and all checked out fine. Any help would be greatly appreciated.

I'm not sure, but can't you access the fuel door lock from the trunk? It sounds as though its sticking from cold or bound up from when you replaced the elements. I hope this helps some!

I'm not sure, but it sounds like you are loosing vacumme when the car is off. Try putting a guage in-line and check that the vac holds. You might see of the lines to the reserve tank (in the trunk) were properly connected after the lines were replaced.
