HPTuners PID Config. Volts/.0371 + (-13)
The threads in the sensor are parallel, but the correct pitch. Just run a 1/8 NPT tap in them until it bottoms out and you'll be able to thread in a pipe nipple.
Pin 1: Vout
Pin 2: Ground
Pin 3: +5vdc
If you don't want to tap into an existing +5vdc source you can make one on the cheap that works very well with a 7805 voltage regulator and a couple of capacitors that can be picked up at radio shack. The sensor has such a low current draw that a heat sink should not be necessary.
Also, I have found these sensors that include a connector and pigtail that might work as well, I haven't used any of these so I don't know anything more about them.

Both of these advertise 0.5v-4.5v linear outputs where 0.5v=0psi and 4.5v=100psi so if those are right the PID equation would be:
Volts/.04 + (-12.5)
