Hi folks,
I'm having an issue with the driver's door, fuel cap and trunk locks. They all are slow to disengage and the fuel door has jammed locked before. I've since bent the loop in fuel area out if the way so it is always unlocked.

I'm sure this is vacuum related but not sure where to start. Any ideas or a diagram would be helpful. Thanks.
