how the hell do you change that thing lol

ive been suspecting its been going bad for a while and just yesterday i spent tow days replacing my trans mount, secondary cross member bushings and torque arm bushings, and when i fire the car up i hear a hissing and take a look, the vacumn line off the regulater blew off and was spitting out fuel.

ive looked at it. has stars screws with the bump in the middle, heard it needs to be taking to a dealership, but i dont wanna do that. sooooo has anyone replaced one before,

Changed the one on my '91 Firebird V6 3.1 just two days ago. The diaphram had ruptured but wasn't spitting fuel as bad as yours. It's not difficult to change if you have the right tools and it comes with instructions. The only catch is the price. Got mine at Autozone for $76. Ohm your fuel injectors. I changed out my FPR only to find out some of my injectors were bad also. Just ordered some from Southbay. Good luck.
