is there any benefit to having a returnless fuel rail system? i have the rails and crossover and not sure with i want to do it. i currently have a 03 silverado ss with the tbss intake and a fabbed crossover. what would i need to make the swap? is it worth it?

thanks

 

I would keep the return style setup that you currently have. It will support more horsepower with fewer modifications to it than a return-less style system.
Only side affect is that the fuel absorbs more heat from being pumped to the rails and then returned, repeat cycle.

 

Like stated keep the return fuel system..

 

got it thanks guys did some reading also and agree.
