I drilled out the opposite port once and put a nipple in it. As long as you don't drill it too big, it should work fine. Drill out the inside between the 2 ports for the reserve and normal positions and it should flow alot more.
I guess you could get another banshee petcock and mount it facing the inside of the tank and make a mechanical linkage so that you turn them both on at the same time. Then you wouldn't have to worry about forgetting.
If you want a response send him a pm. Tell him the following:
His wife is ugly
Cali is full of fags
Android > apple
He shits too much
Sniper/passion > shearer
He's a peasant
That'll get a response
