At the drivers side fuel rail, screw a long line fuel psi gauge on. Unscrew the gauge and you have a nice long fuel line. With a jumper wire connect the grey wire to the back side of the alternator using alligator clips. That wire will energize the fuel pump and drain your pump gas. The wire is by it's self next to the A/C dangling next to the green tach lead. Becarfull there's a lot of psi there.
