Magnafuel pump is fuel cooler needed? Street car I am trying to decide what fuel system to run. I've ran the double pumper system before but don't really like the idea of relying on a second pump to turn on. If I use something like the magnafuel pump, will the fuel get Hot? If I run a fuel cooler will that be enough? Or is double pumper kit just a better option. Street car 700-800hp procharged.

No, do not add extra lines, coolers, fittings, places to leak to your fuel system. This is the last place to add that stuff.
Put two $87 walbros in the tank, and use one for daily driving, have the second one kick on after 5psi of boost or any other window switch setting you desire, and it will not get overheated. Especially if you keep plenty of fuel in the tank. You shouldn't have to spend much more than $250 in the tank to fuel 600RWHP engines these days. If you really are pushing 700-800 though you might want a third pump or use two of the higher quality in-tank series (that flow more).

If you have only one pump, and it fails under boost, your car comes to a stop.
If you run 2 pumps, and a hobbs switch, and either of the pumps, or the switch goes bad under boost, your engine goes lean, and you are having to rebuild, or replace it.
