Ok
first you need a transit visa to go through Saudia arabia, i
and since iti is going to be your first time going through, expect to be delayed by about half an hour on the entry points to Saudi.
but for that Everything else is smooth sailing.
The drive , barring any unforseen incidients on Border points, will take you about 7 hours, if driven on a 130 kph speed.
Good luck
