i just rented a fuel Psi Gauge from my auto store and i followed theshiny fuel lines to behind the alternator and found a spot where it should fit, it has a black screw on plastic cap, and a schreder valve, i can push the side of the guage that goes into it, on to the piece and gas will come out but, the screw on theGaugepiece is far to large toscrew onto the piece on the rail... any other spots? or i gota get one with a smaller screw on peice

You just need the right size end on the fuel hose. That isn't a goofy size schraeder or anything... surprised that you would have gotten one that doesn't work?

^Not true. Ford has an uncommon size shrader valve on the old fuel rails. Most of the kits you rent at an auto store include the small Ford adapter, but if not you can buy one or make one like I did. It's definitely a smart investment if you plan on having a lot of Fords. I've loaned mine out 3 or 4 times at the track. I will check mine later on at my shop and tell you what size hoses and couplings and s_hit if I think about it. I also made my hose a little longer so it's easy to read from inside the car. I can put it right up to the windshield.
