Well let's think, what kills fuel pumps? wear and tear, probably? what is going to have more miles (and thus wear and tear) on it? stock fuel pump, or a new walbro, or a new accel? what happens if the stock pump dies in a accel install? then your car is sidelined, even though you've got a brand spanking new accel in it. if you replace the old stock pump with a brand new walbro, I think the odds of having a pump dying on you are cut down a good bit (its called insurance).

Assumptions without knowledge? you make them all the time.

I am talking about replacing the Accel pump with just the Walbro since intank pumps are simply capable of making more power. Inline pumps only increase pressure, not flow, since you are still sucking a bunch of gas through the same shitty stock pump that is only good for a NA motor. As soon as you get your megasquirt and actually have a real engine management system and get your fuel pressures down to a reasonable level, your inline is completely superfluous, so why even bother with one in the first place? an accel + walbro on a stage 1 kit is EVEN MORE pointless. Get the walbro and sell the accel to someone like trickee.

And the same logic doesn't apply to turbos, manifolds, whatever the fuck crazy conclusion you wanted to jump to. Fuel pumps are a much simpler matter then turbos. You have a voltage-output curve and thats about it, no turbine and compressor maps and eighty different trims, turbines, compressors, wheels, ball bearing vs. journal bearing, etc... Putting a large fuel pump on a modern EFI motor is no big deal.

on the topic of blinky AF gauges, any half decent wideband has a narrowband output that will let you drive the AF gauge. Doesn't need to be as accurate as the digital readout you can get on your laptop (the one you will be using for tuning anyway), and they are easy to see at all times of day. The problem is not with the gauge, it is the signal. if you have one, keep it, it will be useful once you have a wideband.

and even though you are the type of guy who can't stand not having the last word, here's the cole's notes: either way, stock pump + inline or stock pump replacement with a walbro will both work. I like the replacement idea, trickee for some reason wants you to have both, but he's a bolt-on queen so he likes having as many parts as possible attached to his car. Get whatever you want, and it will work.

btw, my car is turbo, but fabricating half your parts takes a very long time. pics coming when I finish it.
