I run an 81 pace arrow same set up..
I just put an old holley system on it until I get my GM 7747 system
done.
I run the 6 port fuel sw so it will return to the tanks 1-80gl and
1-30gl.
And I use the masters 2182 inline pump on the frame after the tank sw.
I'm using 3/8 feed and 5/16 return. I have only done local trips so far
but have not had any problems.
