On my pro-touring '78 TA I ran a sumped stocker with pre and post pump filter, Vette regulator, and single line to the front. Pump was a Bosch 044...fantastic pump.
Never let the tank get below 1/4 tank I don't think and just drilled a ton of little 1/4 holes in the bottom of the tank before welding on the sump. Worked well for what it was but if you stopped really hard you could hear the pump change sound for a second then recover.
Good luck!
