If you use solenoid-style pumps where a coil drives a diaphragm (the kind
that go click, click) then you don't need check valves because it alrady has
a valve in the outlet. If you use a centrifugal pump, like the holley and
carter pumps, where you hear a motor whirr, then you do--they don't have an
outlet check valve and will backflow if one is off. If you don't have check
valves then you are actually reducing the reliability of the system by
having two pumps--more stuff to break and a single point of failure.

Good stuff, keep it coming!
I have a question for those who are running two fuel pumps into a tee.
Is
there any need for any kind of valve between each fuel pump and the tee?
I want to install a system similar to the one Rocky has described, but I
was
planning to use two Facet-style fuel pumps.
All opinions welcome!
