Sorry, no pics at the moment. I'll try and describe my set-up as best as possible.
"T" fitting is placed upright at the back of the carbs, just above fuel inlet for 1&2 carbs. Single line from petcock attached to the left arm of the "T". 1&2 inlet line is very short(less than 2") and attaches to the bottom leg of the "T". 3&4 inlet line is about 5" long, or "just enough" to reach the fuel inlet. The shorter the length of line to 3&4, the more the "T" will tilt to the right allowing gravity to do its job getting fuel to those carbs.
