You'll want to check the capacity of the pumps, you need to make sure they can deliver enough gallons/hour. You need that in addition to the correct psi. You also need to be sure that the pumps are compatible with the oxygenated gas blends that are currently available. 
I use the solid state Facet pump, with a regulator set to 2 psi. The identical pump is available from NAPA as well. It's relatively quiet, but the reason that I chose it was that it is compatible with gasoline/ethanol blends. I used to use a non electronic diaphragm style electric pump. It made a noticable thump thump thump as it was working, which gave me a heads up when it failed. Those failures became more frequent once the gasoline changed (1st pump lasted 10 years, last pump lasted 6 months). The electronic pump in the car now is 13 years old (and yes, I carry a spare).
I mounted my pump under the tank in the trunk, near where the home market PI pump went. No weather worries there. Got a fuel filter in there as well. I also routed the fuel lines along the right side of the car, as far away as possible from heat, and up into the engine bay.
