Fuel return line routing

Is it ok to run my return line back to a "T" at the inlet side of my fuel pump?

Nobody? It's a 2004 5.3L in 2001 Mustang. I'm running a Walbro 255 pump.

I assume you are running an external/inline pump. I would say that it is not the best idea to reintroduce hot fuel directly back through the pump, and that it should be routed back into the tank first to allow for cooling before it is cycled through again. My 2 cents....
