I have a pretty simple question for anyone who mouight have the answer. I have a 96 SS and I recently started noticing some bad hesitation when exceleration. I check the fuel pressure and it's reading about 35 at idle. even if I rev the engine up it barely gets to 38 or 39. Is this an fuel pump regulator issue or a fuel pump itself problem

I dont have an answer for you, but I think yours is headed in the same direction mine went. After the whole hesitation one day it started backfiring and running crappy. Then stop running. Won't start. I have replaced fuel pump and it's still doing same. I did not think of regulator though.

^^^^ adding to the above, when my regulator went i never actually leaked into the vacuum line. it only leaked through the joint on the outside of the regulator. just fyi though.
