UPDATE! I went back in and with the new information, I decided not to do that block plug, I plugged the hose up and just let it run through for a few minutes, then i went back with copious amounts of Distilled water to flush out the tap. I then let that drain, and filled it back up with the Gold. I was able to get about 3.15 gallons in there before it hit the MAX line. I am going to drive it around tonight and see if it will need a top off.
