Grant,

I made a small sump and welded in bungs for the pickup and return lines.
I cut three 3/4" holes in the bottom of the tank and welded the sump over them.

I'm running a carb, but I have had no problems at all with fuel delivery, or heating of the fuel.

FI may indeed add more heat to the fuel, so you may need to run the return in at another location.
It's still best to run it in near the bottom of the tank to avoid aeriating the fuel.

Good luck,
