Loose gray wire at firewall is the fuel pump prime wire.

Loose gray wire at firewall is the fuel pump prime wire.

Should have a female spade terminal on it, and if you connect +12V to it your fule pump will run.
This is the shortcut to setting your FP with the engine off, not having to disconnect your vac lines.
