Ok, I've looked all over the place and I can't find what I need... :bawling:

Well I sort of found what I need, but I am NOT going to pay $36 for said piece!!):

http://www.mcmaster.com/param/asp/PSearch2.asp?reqTyp=parametric&act=psearch&FAM=ssppf&FT_138=29163&FT_1375=57317&FT_140=935&session=ssppf;138=29163;1375=57317;140=935&ScreenWidth=1152&McMMainWidth=815#

Basically I want to remove the Schrader valve on the fuel rail and turn it 90 degrees and plumb it to a pressure gauge.

I could probably use this, but I'm not a fan of hard tubing (mainly because I suck at bending it and it looking right... :( )

I also looked all over for the same piece, and could not find it. You want to run the cobra intake with the MarkVIII fuel rails, right? What I ended up doing was just removing the standard cap on the schraeder valve and using a regular tire valve stem cap, and then I had to grind a little bit on the intake itself to get it to clear, and it works, but I have no way of checking the fuel pressure.

Yes I am. :D I thought I would just put in a 90, plumb it to a gauge mounted on the side of boss for the IAC valve (since it already has two holes and a nice smooth mounting area).

I can't believe that part doesn't exist in brass!! :beek:

I may just end up using the tube and plumbing it with hard lines.

Yeah, I looked everywhere for it and had no luck. I even found something on ebay that said it was 1/16" NPT, but when I got it, it was too small, so I don't know what it was. In the end I just left it alone figuring that with a stock fuel pressure regulator it shouldn't be an issue.

use a 1/16 male to 1/8th female and then run your gauge/elbow. That is what I did.

Are you trying to look at the gauge from above or from the side? Straight up seems easier to me?

I dont remember having a clearance issue with the schrader valve on my Cobra intake swap .. it is just non-accessable. (using 97/98 Mark rails )

I don't have a clearance problem, but I A) want it to be accessable, and/or B) plumb it to a gauge.

Can you post a photo of your setup with the 1/16 to 1/8 fitting on the 97/98 Mark VIII fuel rails with a Cobra intake manifold bolted down. :thumbsup:

You have about 1" of clearance between the fuel rail schrader valve fitting and the bottom of the IAC valve mounting pad. The schrader valve barely fits.

Is the schrader valve 1/8 NPT?

Want to put fuel pressure gauge on my Tbird fuel rail.
