I have a standard fuel pressure test gauge (from auto zone) that fits the larger schrader valve size pressure testing ports (like what is on GM cars, at least older ones). But it's too big for the port on my 86' GT. If I remember correctly it came with different fittings, but I've lost them over the years. What size fitting can I use to hook it up to my 86' GT. The link below is to a picture of the fuel pressure valve (to the right of the pressure regulator) on my car so you know what I'm talking about.
Maybe thats the wrong place to attach the gauge, but I don't see anywhere else on the feed line to put a gauge.

Link to the gauge I have so you know what I'm talking about. It's not the exact one, but it's similar.
