How to drain the fuel?

[89mulletbird]

I want to drain the pump gas out at the track, out of the fuel rail. I have a fuel pressure gauge with a drain hose on it. What pins on my service port under the dash do i connect to engage the fuel pump?

ya dont need to do anything under the dash. There is a gray female plug by the alternator with nothing pluged into it, get some wire put a male spade connector on one end and an alligator type clip on the other. Plug the male into female and jumper the other end to the back of the alt.

This is the same port I plug my scanmaster into, correct? I can look up the pinout. Do i ground or hot wire the fuel pump pin?
