I used to have two pumps in the rally car, and I think it's done purely on the basis that if one fails, you still have one there to get you back to service.

I was gonna run two lift pumps, and two fuel pumps, but I can't be arsed with stuff going wrong, so have just gone for the one group A.

This is the Reyland Escorts old setup, two pumps on the left and fuel filter on the right.

If you have 2 new standard pumps then no reason not to use them in this way, but one Grp A pump is neater, also if it fails the engine stops, if you have 2 std pumps and one of them fails, well you can guess what might happen if 1 pump can't supply enough fuel for the engine...

I can't give specific advice on your setup, but generally 2 pumps are run in parrallel (wes's pic) as a fail safe system. A common cause for engines 'letting go' is lack of fuel (running lean). If you are running the 1 pump, and lets say it fails at 7k rpm...... The chances are the engine will have breathed it's last.
One thing i would advise, is use pumps that have enough fuel delivery for your engine, if used on their own, for the reasons above.
