EFI Fuel Pressure Regulator Part #

[Kilonzo]

Hi, this is my first post since joining. I have a 1989 Festiva with automatic transmission and the 1.3L engine. I have googled extensively but not able to be sure that I am getting accurate information to keep from ordering the wrong part. Any input as to the correct part number and suggestions as to the best place to buy from would be appreciated.
