Why two fuel pressure regulators?

[AndyYTJ]

I searched too see if this had already been discussed but didn't find anything, so I'm sorry if this is repetitive. 1997 Jeep Wrangler with 2.5 4 cyl. While attempting to remove a stuck on fuel rail to replace the injectors, I ever so slightly bent the rail. Not wanting to risk it, I've purchased a nice billit aluminum one from fasster.com. his doesn't have the regulator on the rail like mine does, but I'm not sure what that one does anyway. My rail does not return to the tank. I've replaced my in-tank pump many months ago and it has the regulator on the top. What is the purpose of the one on the rail in the absence of a return line, and can I be comfortable with deleting it?

Isn't that a pulse regulator

I'm not familiar with a pulse regulator, so it very well may be. What does a pulse regulator do, and what problems could I cause if I deleted it, in your opinion?

You'll be fine without it. It's supposed to keep surging fuel pressure... it's not really a problem that needs solved.

My 97 doesn't have one and runs fine.
