I run a electric pump from a earlier model Corvette. I have sealed breathers on my valve covers that are both rooted under the coil pack to a T fitting, from the T fitting it is routed to my vacuum pump underneath the car on the driver side close to the headlight. The system doesn't pull enough vacuum to warrant a catch can before the pump, but it works well enough to vent any extra crankcase pressure. I used to have a catch can under the hood with this system, but it didn't grab a dime of oil, so I got rid of the catch can and routed it directly to the pump. Which to me is x1000 times better, because I can't stand the smell of oil vapors coming from the K&N on the catch can into the interior of the car. The line coming off of my electric pump has a line which is routed into my frame and atmosphered there.
The link below shows the pumps you can use with the wiring harness Racetronix makes for the system. The rest is just a set of sealed breathers and a trip to Home Depot for rubber lines and a plastic T.

Tools needed

Heat up the base with a heat gun and remove the lid

Remove the diapharm seal and spring. If you don't, oil will shoot up your oil dipstick all over your engine compartment.... Ask me how I know.

Next remove the foam to give more vacuum

Seal it back up and silicone the base to seal it all up, no leaks.

drill a hole in the center of each valve cover for a grommet to fit in when your breather is in.

This is what it looks installed on the car. Both valve covers run to a T fitting underneath the coil pack, then one line to the pump.

I mount it in front of the driver's side headlight and run the line from the T fitting to the pump. The pump has a in and out port. The out port I run a line under the car into the frame so I don't smell anything.
