Limit of stock fuel pump
Where does the limit sit with a stock fuel pump before needing to step up to an electric one? Would assume it is a combination of capacity/power
output and intended use? Any rules of thumb?

My rule of thumb would be......stock fuel pump, stock engine.
I'd rather wear a Beetle out by racing it than by polishing it!

Intended use does affect what you can get away with, i.e. if you only potter around the streets with short blasts the stocker might be usable on a
150hp engine, take that same car down the long straight at a circuit or strip and you might starve it by the end. Some guys manage to run them in
12sec street cars but thats really pushing it I think. If you do replace it make sure your regulator is suitable and the replacement pump is actually
an upgrade. The CB ones are ok I believe.
Also if you really need a bigger pump you probably need bigger lines as well. My 2c anyway

Dunno why people are so scared of stock pumps.
Plenty of folks out there running IDAs and stock pumps.
Classic example is Glenn Rings 2180, pumping out 200ponies with 48IDAs on a stock pump for decades.

Interesting - thats a good number 
I like the idea of a stock pump for simplicity/reliability. Dont like the added wiring required on an electric one. Making sure cut off/prime etc
still works and its safe.
Are there any mods required to the fuel tank to prevent vacuum when using larger lines and/or elec pump?
