Fuel pressure testing

[Horn]

Anyone run a fuel pressure test on a later TJ?  Not sure when they changed it, but the later models don’t have a schrader valve on the fuel rail.  Haven’t found a ton online about later ones but 1 video described disconnecting the line before the rail and creating an adapter to tap into.  Just curious if anyone has done it before I start disconnecting things. 

This is the info I’m running with so far. 
Seems reasonably straightforward.  I have a pressure testing kit.  Suspect I need an adapter for the connection like he shows.

I have a really fancy but cheap fuel tester setup with tee fittings that go into the fuel rail if you want to borrow it

If it’s more than I’ve got here, maybe.  I have a t-fitting.  It looks like he used another quick connect and a tube to make an adapter to connect to the T-fitting.  Am I correct that the connection on the fuel line will need an adapter to connect to my t-fitting?  I haven’t taken it off yet just to not open up a can of worms until needed.  Seems like a piece of tubing and some band clamps will do to connect on the rail side of the T. I got side tracked for the rest of the day after looking at it and groaning at the lack of a schrader valve to make life easy.

You'll have to put the gauge inline before the fuel rail. I did this on my LJ a few months ago. I don't recall the specifics, but iirc my kit had what was needed to do so.

I picked up a few things today.  I think with them and what I have in the kit I can make it work.
