I ran my ute out of fuel just the other day... You'd be surprised how long you can drive it for with the fuel light on!
She literally stalled as I pulled into the servo not even joking, rolled into the bowser in silent mode... Very funny moment.
Anyway I just filled it up (took 77.3ltrs) and used the manual primer until it was too stiff to push any more, it does take a few minutes. Took about 5 long seconds of turn key cranking for it to fire up, all good happy days
