I don't trust the PO, regarding fuel lines Options

[Always Looking]

Hi All,

I want to replace every fuel line in the vehicle, except the ones through the center tunnel - they are pliable and soft. I have some basic questions regarding sizing (since I don't trust what i'm taking off.) Based on some of the searches, I will definitely use the FI hose clamps and will probablly use the standard sizes of fuel line (as opposed to the metric ones). I have a 72 1.7 with the different size tunnel fuel lines and the pump moved to the front under the tank.

5/16 from tank to filter to pump to tunnel?
5/16 from tunnel to rail to injectors to other rail to injectors?
5/16 from rail to pressure regulator?
1/4 from regulator to tunnel?
1/4 from tunnel to Y (1/4 to tank, 5/16 to pump)?

Also, do you just FI hose clamp to the plastic tunnel lines in the engine compartment or am I missing a fitting?
The car has the box fuel filter, but I think this is the wrong one.
The PO had 3/8 line from tank to filter to pump to tunnel (which is where it slipped off and leaked gas in my garage (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) )
