The manual is available for download in mechanics 101. Also the search function is available, use the google option.

i have a 92 600 f

theres a fat 15mm ish vac going to the air filter and a smal vac line from the rear of the petcock to the right hand carb ( number 4) at the top on the right of the carb

if its the same as mine.

There is only 1 vac line port, right side of carb 4, goes to the back of the petcock. Tank lines are either drains or vent tubes, route to the ground. 2 vent lines on the carbs, toward the engine, route over the airbox through the clips to the ground. Now if you have the Cali smog equipment, remove it.
