LT1 to LS1 fuel system

I'm not sure exactly how the fuel system is supposed to be modified
The car is a 97 LT1 Z/28
The motor is an 01 6.0 with LS3 heads, custom cam, 1 7/8 headers, FAST 102 intake and Holley 102 throttle body

I have a 340 stealth fuel pump and a corvette regulator
The old walboro pump was mounted inside of the stock GM shell
But the new pump doesn't fit inside of the GM shell (shorter pump)

I've seen where someone mounted the pump straight to the pump bracket, but where would the other lines go to

Thanks
Rob

What injectors? If they are big enough to run at 3 bar, I'd just change the data in the tune and keep the return system.
