Sending unit swap for EFI

Good morning fellow C body people. I am going to put the Sniper Fuel injection on my Monaco. When I did this to my 66 Polara I had to drill a hole in the tank for the return line. I'm trying not to do that this time by seeing if anyone on here has any information on a 3/8 supply sending unit with the built in return. I see those were available but I think just in the A and B bodies. Would they fit?
