Hi Guys. Just wondering those of you that have wagons with LS swaps if you have the 3-port or 4-port Astro pump/sender. Seems like the earlier EFI models are 4-port, and the later ones are 3-port. Thanks.
3 or 4-Port Astro Sender?

Pretty sure I used the sender from a 1987-95 model year. It may have 4 ports, but I can't see needing to use all of them obviously. And One is HUGE.
I don’t have fuel injection but I run a in tank stock Efi pump I run a Monte Carlo 4.3l fuel injection tank and sending unit and installed my cutlass fuel neck, with a return style regulator it works really for my quadrajet carb it has 3 ports pressure,return,and emissions witch I also have hooked up
I dont think you have that tank in a wagon. the astro sender unit is an alternative option for us wagon guys that cant get a repro sending unit.
