What power level do the factory fuel lines become a limiting factor and need to be upgraded?
Or what kind of power are some of yall making on stock fuel lines?

Unreal

Pump or e85? Meth or no meth?

Assuming no external pump/lines?

Return line or no?

Adjustable Pressure? Rising Rate?

Could be 800 or 1000+ just depends on a lot of stuff. Typically when people upgrade fuel system adding a line is cheap/easy compared to the pumps/etc so you don't see people hitting the limits of the factory feed.

I plan on going pump without meth with a single walbro 450. I will have a return line and a rising rate regulator.

I just don't want to upgrade the fuel lines if it's not needed.

What are you going for rwhp wise?

Unreal

Factory feed line will support more than a single walbro 450 can ever put out. Hell the line is as big or bigger than the fuel pump outlet. So I can't see any need to even consider it with only a single walbro.

I'd like to see 800 but we will see, I'm thinking I'll stop around 15 lbs.

The outlet may be smaller but the feed line is much longer which create more friction/pressure drop.
