optichris Posted October 17, 2007 Share Posted October 17, 2007 is 89 a TBI or with a fuel rail? I just replaced the fuel pressure regulator on my TBI 86 and it was a piece of cake. You do have to pull the throttle body from the truck. Once you do that, no problem. Link to comment Share on other sites More sharing options...
