Gather the following:
The pump
A 0.1 microfarad film capacitor (AKA polyester capacitor)
A 1 amp diode (any voltage rating over 20V will do)
An inline fuse holder
A 3 amp fuse that fits the fuse holder
A male Molex connector.
1. Solder the following together:
the positive lead of the pump
one capacitor lead
the end of the diode with the stripe
one lead of a fuse holder
2. Solder the following together:
the negative lead of the pump
the other capacitor lead
the end of the diode without a stripe
a ground lead (black) of the Molex connector
3. Solder the +12V lead (yellow) of the molex connector to the other lead of the fuse holder.
4. Insulate everything.
5. Install a 3 Amp fuse in the fuse holder, and it's ready to go.

You probably have several groups of four wires coming out of the PSU and going to Molex connectors. Isolate one of these cables, and don't use any of the connections on it for anything other than the pump. (and fans or other insensitive hardware)
