The MOTIVE pressure bleeder can be used dry or wet. You can fill the tank with the brake fluid and not worry about running dry. Be sure to test the cap on your reservoir dry before adding fluid. This will ensure you dont leak fluid out the cap when pressurized. I put rags under the reservoir and cover it in case a leak blows off. The service manual on the 5th gen uses this type of bleeder up to 30 psi but I can't say what the 6th gen manual says. Here's some videos.
