A lot depends on your pump. In my car if I had one pump off I could only get
about a pound at the fuel pressure gauge. My system might be more
restrictive than others. With check valves of course I get full pressure. I
figure if I'm going to have two pumps then the redundancy should be a
benefit.

People have said checkvalves are useful, but I don't have any.
Yes, if I run only one pump, it will pump down the line to the other (as
well as to the front).
But I run both at the same time. It is less for redundancy (it is that too),
as it is picking up fuel from whichever side the fuel happens to be in a
turn. Even on long carousel turns on a low tank late in a race I have had no
problem (HPT's is a left, Memphis's is a right.)
But if you want, checkvalves can't hurt.
