Well to make a story short, I had an autometer sender that simply screwed onto the schreader valve on my stock fuel rail when I had them. My new mmr rails don't have a valve obviously, and I still wanna keep my interior fuel pressure gauge so Im gonna need a special AN T fitting to splice it in the line so I can screw this autometer sender onto, does anyone know the specs of that valve.

It's a TR-6 Schrader valve, 8mm OD (nominal).

The OD thread is 0.305" x 32tpi, the ID 0.209" x 36tpi.

The metric thread dimensions are often listed as alternatives (7.70mm x 0.794mm pitch, and 5.30mm x 0.706mm pitch)--do not be confused by this, they are just metric conversions of the actual English unit dimensions.

The thread in the OEM rail is 1/16" NPT...
