Im just reiterating what most on here say to use for feed/return, especially with a bigger pump than their smaller one. Cliff insists on 1/2" at this power level with elect or mech pumps... but then again you said you dont plan to do any drag racing and running most any tire on the street will break free way before the G forces come into effect, and the main purpose of this set up for you is to price the carb after sitting for awhile.
For your application 3/8 will probably be ok.
