XJ Ask the Question Thread
This thread is for all those who would like to ask something tech related and don't want to start a new thread or hijack someone elses, and for all those tech related questions you happen to ask in the big off topic threads. Me and some of the older members will answer every kind of question as long as it is TECH and polite.
P.S. for the newbs: stupid questions don't exist, there are only stupid answers. Feel free to ask whatever you want. "What is a Jeep?" is a good question....
EDIT: If your question is very common (eg: lift) please DO A RESEARCH FIRST and if you don't find the answer come back here, 75% of the questions can be answered within a 5/10 min browse using the "SEARCH" button on the black banner menu.
For any lift & tire questions go here first: https://www.cherokeeforum.com/f2/all...go-here-10579/

Id rent a fuel pressure gauge from an autoparts store and check your pressure at the fuel rail. That will gibe you the pressure after the regulator.

I have no idea what a pulse dampener does. Helps keep pressure consistent? Some of these things on the 99 are so foreign to me.
I'm not having issues or anything I just seen it and had a wtf moment.
