Then your return line will come off the regulator back to the cell.
Easy.

regulator needs to be close to the CARB, right. pump needs to be near CELL. that means an extra 8-10ft of stainless 8an line !!!!!! $$$$$

Yep, also remember the pump is gravity fed. Install under the tank.

hell yes, consistant pressure, pump lasts longer, quieter and no pressure
creep. Spend the money and do it right the first time, don't make my
mistakes.

-8 line will feed atleast 800 horsepower. Make the
return line -8 as well and you'll have no problems.
-10 would be for something really serious. I have
friends that run bottom 9's with -8 line. I also know a
guy who went 10.40's with -6, kinda crazy but he did it.
