Fuel hose diameter for lines from intake to quick disconnect under brake booster. Also, size of quick disconnects. I can't seem to find replacements anywhere.

If we can get a closer picture of what you are talking about it would help. I believe what you are talking about is 3/8 size hose.

Looks like they may be quick connect that plugs in by the fuel pressure regulator then goes over the motor and sneaks down and has what appears to be the same hookups under the brake booster. I was wondering what size hose is these were and what size connectors? Also, I am having a very hard time finding any type of fuel lines for this car. As you can see somebody compression fitted one and I am definitely not a big fan of that.

Yep, those plastic fuel lines are a bummer. I have seen people use a two-way connector and hose clamps or a compression fitting as shown. You can try running a new fuel line from the tank forward, but you will have the same problem of size and connection. 3/8 or 5/16 will be the sizes needed.
