'72 Demon, Stock Tank - Elec. Pump & Filter mounting?

1- The regulator is on the return line before the tank
2- If I grenade a trans, I'd rather have the line on the outside.
3- Ran braided line up the inner fender and it is shielded.

Is there an advantage to having the regulator on the return line?
I always thought you wanted it regulated just before the carb?
Understood on the trans exploding, and understand now going up the inner wheel well.
Nice work, definitely gave me some ideas, I really appreciate the replies!
