not nearly as difficult as one may think
grab the entire efi line setup front to back from an efi car.
get yourself an 86gt fuel sender, that's the ONLY year that will work right otherwise the 87+ senders will read backwards on the fuel gauge
go to foureyedpride.com message forums, a number of the guys there have updated their four eyes with efi, and can walk you through the entire process step by step.
