My plan was to have 2 pimps in the sump tank with fuel return to the sump
tank. Iplan ning to run the engine on the test stand with a duplicate of the
A/C fuel system. Any input?

Having the pump in a 'sump tank'  is a completely different scenario than
pump in main tank.  Don't do this thinking that it is a tried & true
solution.  Might be OK if all other factors are considered but there are a
LOT of them.

This would not prevent a return system from being developed and installed. Unless you intend to put an RX 8 pump inside your sump tank...it might not be a bad idea to plan for one.
 
Speaking of.. Anyone actually DOING in-tank fuel pumps. As popular as PL is around here, I gleaned from his list that having an in tank pump can help prevent vaporlock by not having to "SUCK" fuel. As long as the tank remains wet (or the fuel air mix too rich) it should be safe.. right?

Something to consider...
