upgrade fuel return line?

[red97gsx]

I've searched and not found what i'm looking for. I'm trying to see if i need to upgrade the return side of my fuel system. I built the motor, upgraded the feed with a -6 and a earls high flow fuel filter and will be running 880 injectors to a aeromotive AFPR. Do i need to upgrade the return line? Car will hopefully be about 435 awhp range. Let me know if you need more info of what i have done so far. Thanks in advance

If your fuel pressure stays where you set it at idle then you don't need to upgrade your return.

If you can't get the pressure to go low enough, you need a bigger return.

It's that simple.

That was how i was going to judge it myself, i just did not know if it was a known fact of it needing to be done or not. Thank you for the input
