Schrader valve???

I'm not trying to tap the fuel rail. My kit is the NOS 5116 Dry Kit, and it comes with a Fuel Pressure Safety Switch that installs in place of the schrader valve on the fuel rail. I have access to a mechanic at work and had him look for it today, he couldn't find a schrader valve and wound up printing a fuel rail assembly diagram from an '03 and sure enough there is a schrader valve, I'm assuming they changed it up for '04. My system won't work without this switch. I have no clue what to do. I've called NOS, and they are closed, the place I bought it said it would work on an '04 without a hitch. Any help would be much appreciated. Thanks

Schrader valves are not present on 04 Mustangs. 03 was the last to have them.

yea that's what happened to me when my kenne bell kit came with new fuel rails. I'm like wtf :shrug: called k/b they said ford no longer produces fuel rails with the schrader valve. So I had to order an adapter that goes on where the fuel press. transducer relay mounts on to the drivers side fuel rail(this was for my fuel press. gauge)
you might call up k/b and see if you can get one. should work fine for your switch.

here's a pic of the adapter:
