Installing fuel pressure gauge on the fuel rail?

[Defcon92]

I'm looking at installing a small fuel pressure gage onto my fuel rail of my 1992 cherokee however I'm unsure of the size of the nipple/shredder valve. I believe its a flared type fitting? Can anyone use there magical googling power and find the correct 90* elbow I'd need?
Would it be a female 1/8" flare fitting to a female 1/8" npt?

I'll be using this marshal 0-100 psi gauge which has a 1/8" npt fitting.

Do a search on here. I know there is at least one person that has done it. They used an adapter of some sort and IIRC removed the schrader valve.

i did that and i have to tighten it up regularly. it vibrates loose about every 500 miles. going to weld a female fitting on the end of the fuel rail this time and run it that way

This fitting takes the Schraeder to a gauge:

This gauge is cheaper and pretty nice:

The fitting does warn not to leave a oil filled gauge on or the vibrations will eventually crack the fuel rail. I just put mine on for diagnostics and then took it off. Also, the Schraeder side leaked until I used a few turns of the thick yellow teflon tape on it.

I'm not sure if your fuel line connects to the fuel rail with the same connect or as me but this is what I used to isntall my fuel pressure sending unit.

That's a really nice piece, expensive, but nice.
