On the Fuel Pump questions. I would never run just 1 fuel pump with boost. If for some reason it shuts down it could be a very expensive lesson to learn. You want to OVER fuel pump it. Tons of guys on theturboforums.com use the Walbro GSL-392's. They pump some serious fuel and are good up to 600 Boosted EFI HP Each. They cost $100.00 each, are quieter than the Magnafuel, Aeromotive etc. They will lift fuel, act as a dead head if you are turning multiple pumps on at different times "Boost or NOS" etc and are Super Reliable. No Fuel Pump Controller needed!!
I am running Triplets on mine. Dual 10an feeds off the Fuel Cell to the Manifold with a single 10an to the regulator, 8an return. This set up is good for 1600 Boosted EFI HP and cost right at $500.00 for the manifolds, fittings etc to set up.
i strongley disagree with this therory, Actually its opposite If you run one pump and it stops working your engine shuts off with no fuel to burn(been there done that)no harm no fowl. If you run multiple pumps and one stops working you take the chance of leaning the engine out and burning it up
X2 = Single belt driven pump is the best if space permits.

On a Street Strip car, what about the Semi Truck that is going to T Bone you because your car died in the middle of the intersection?? Very Expensive and you could loose your life in the process also. Just something else to ponder on.

seriously? What about that throttle cable your going to use, or even the ecm could go bad, or the battery wire could fall off or the trans could break or...............................
maybe you shouldn't pull out in front of anybody

But what if a pump dies a 'slow' death, or output starts to quickly drop off, over a few seconds? This could cause a big problem for an engine under boost or N2O, not so much for an NA car. Mad Dart's idea would give an attentive driver a *small* window of opportunity to get off the throttle and maybe limp home. On the flip side, he has 2x as many pumps that might fail.  Not trying to be argumentative, just to understand. (I've had an EFI engine stutter for 2-3 secs due to insufficient fuel, while driving, and it didn't shut off).
Parts I seek:
driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set
16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better.
69-73 C-body caliper brackets and/or splashields

Insufficient Fuel= Getting Fuel but not enough which will eventually and very quickly generate a Lean condition Roaching a Piston, Head Gasket, etc etc ESPECIALLY so in a Boosted or N2O application.
Dead Fuel Pump= No Fuel, So at worst it shuts down and you're walking home with the expense of replacing a Fuel Pump not a toasted engine.
To cover just about all the WHAT IF scenarios that have been brought up. Use a Mechanical/Belt driven pump bigger than you really need. It's either going to work or it isn't. NONE of the Starting to Fail or cutting out which electric pumps like to do.

I think the bottom line is that you need to be smart on the data logging capability and have a channel dedicated to fuel pressure. I was able to identify a weak pump on the dyno and stopped upping the boost until I replaced the pump.

Yes a Fuel Pressure gauge is one of your most crucial gauges when running boost and/or EFI.
Insufficient Fuel= Getting Fuel but not enough which will eventually and very quickly generate a Lean condition Roaching a Piston, Head Gasket, etc etc ESPECIALLY so in a Boosted or N2O application.
Dead Fuel Pump= No Fuel, So at worst it shuts down and you're walking home with the expense of replacing a Fuel Pump not a toasted engine.

Yeah and I should just stop breathing too. I know. I am running EFI so my ECU will pick up the lean condition and the safety parameters I have set will go into effect at that time if my FP or Lamda safety feature's are triggered. First pump is on at start up. Second pump joins the show at 4psi, third pump comes in at 8psi or NOS Hit, whichever don't matter. Of course I can change these setting whenever or however I want in any configuration I choose. This is just an example. I do like the Belt Driven Pump Idea but I have no room. I didn't post what I am doing to start a war but I guess it has??
