I would use the pump Edelbrock design to use with their electronic
injection. The fact that you're trying to feed 360" (over 60 gallons an
hour) a bigger engine than most stock gasoline engine nowadays, means if
you used an in tank pump and especially if you slowed down the flow by
trying put a regular carburated electric pump and that would surely
screw up the return line. On a high performance engine it could lean out
and melt the pistons the first time you pulled for ten seconds, like a
quarter mile, or hill climb.

I vaguely remember an aricle that I read several years ago that dealt
with this same sort of thing.
The guy that did it took the bigger Wrangler tank and turned it around 180
degrees so that he could use the filler location of the CJ. Before
installing the tank, he removed the fuel pump/sender pice from the tank, cut
the old pump free and soldered a newer, higher volume pump in it's place.
Using the Wrangler tank gave him an easy hook-up for fuel return lines as
well as the in-tank baffle.
You don't need a baffle inside but any hard cornering or driving on an
incline could starve the fuel pump when the tank level is low.
Ideally, the fuel pump should be in the tank for longer life, the fuel
helps to keep them cool. That's why the OEM people put them there.
Here is something similar with a stock CJ tank.
