Brute7

hey guys im new and i had a couple questions. I just purchased my first RX7 about 2 weeks ago and im needing some help i think its the FPD (fuel pulsation dampner but i cant find any threads on the dampner for a 91. i know they are different than the earlier and later models and im trying to find out how i would go about replacing it cause it looks like its built right into the fuel rail with nothing to unscrew it, like its a part of the fuel rail. Ill take some pictures of it tomorrow and post them on here but i needed to get some information as to how i would go about changing it out. get back to me asap would appretiate it thanks.
