It is as follows:

.302-32 UNS CLASS 3A
PER ASME B1.1

Go here: http://www.haltec.com/webde...og/HaltecCatalog.pdf
Bottom of pg. 30 has connectors for typical schrader valves. Chances are, these guys will have what you are looking for.

If you remove the schrader valve, the threads in the aluminum housing are 1/4" NPT (national pipe thread). Any hardware store should have the brass fittings/elbows needed to install the guage directly to the fuel rail and most pressure guages come threaded for the 1/4 NPT.
