Getting back to my dart and fuel pump!

I have neglected my dart for the last 6 months. Last summer I got a new electric pump and canister filter. I plan on using the stock tank so I have a few questions.

1. I plan on mounting the pump on the inside of the frame rail with a heat shield. Would this be the best location with a stock tank?

2. Would I be able to keep the stock line from the tank to regulator or should I get a new line?

3. I want to use the aero quip line from from the regulator to carburetor. What size line would he recommended?

The engine is a .30 over 360 with a Holley 750 dp or a edlebrock 650 avs. The car is a street car that makes about twenty passes a year.
