EFI fuel tank module for stock tanks

Whats the benefit of an in-tank pump? Put the pump in a 1 gallon surge tank (not much bigger than an overflow tank in the engine bay) feed it with your stock electric/mechanical pump + fuel rail pressure bypass and run the return out the top of the surge tank back to the rear tank. No chance of exposing the inlet on cornering, and little chance of pump contamination due to fuel sock and stock inline filter (EFI micron rated) prior to surge tank. I must say that it looks a hell of a lot easier to change out than a tank dropping top mount EFI.
