Thanks for everyone's help with my question.

Bottom line -- A single brake line comes off the front of the master cylinder (marked H), is fed from the front chamber of the brake expansion tank and powers both rear brakes. Two separate lines come of the rear of the master cylinder (marked V and closest to the brake booster) and are fed from the rear chamber of the brake expansion tank. This rear chamber powers the front calipers with one line going to the right front caliper and a separate line going to the left front caliper.
