Default Feeding a surge tank

I couldn't find any reference to this when I searched: When you are feeding a surge tank with an in-tank pump from the stock tank, would there be any advantage to adding a regulator in the feed line, to cause the in-tank to have something to push against? Not to regulate the pressure in the surge tank, it will of course have no pressure in it, and be fed by the return side of the regulator. I am just having the thought that the in-tank might need some resistance to operate properly, if only just a few psi. Any thoughts on this? Has it been covered already?

As long as you have a return from the surge tank to the main tank, run it without a regulator. Regulator will add heat to the fuel (pressure) and reduce the capacity of the main tank pump.
