Answer
Hello,


Sounds like a guess on your mechanic's part
I find it a little hard to believe that the problem is a gas filter and sounds more like a fuel pump in the tank losing its prime.

Of course I cannot guaranty that is the problem without being at the car physically to perform pressure tests.

Let's put it this way, a plugged fuel filter will cause hesitation, it will cause many things, but it won't control losing its prime and that is exactly the symptom you are giving me with car not firing up cold.

There should be constant pressure with the ignition on and yet you don't have this or the engine would start cold.
