Since you're a mechanic, does this usually remedy the problem? And have you ever seen someone foul their spark plugs to the point of needing replacement just from running out of fuel?
1) As to "More than one gallon of fuel," the answer is.. I have started car on less than one dollar of fuel after they have run out. Antifreeze bottles on side of road, 1/3 full, after walking 1.5 looong miles TO Gas station, then 1.5 miles LONGER w gas in AF container, back. Sometimes, even less. Not going there. But it started. Car also had time to sit and cool in those instances.. perhaps to "Un-vapor lock" and also Fuel Pump cool down. Perhaps. Though HOT cars still started right away. Depends on the car. And ambient temp???.. idk.
There have also been cars that seemed to need between five and six gallons, plus time to un-vapor lock (and something to cool down, perhaps that pump,) to start.
It can be that drastic. 80% of cars will start on whatever little gallon you put in, though. Anything else is extremely pushing it, but it started after a few cranks (to get the fuel back up to the engine) too.
And that was on whatever Fuel Pump and Fuel Filter was in there too, though "Borderline" fuel pumps, and pressure, could fail. Especially after something like that.
If it gets bad enough, the fuel LINE may need replaced. Though ive never seen that. Just Filter, and pump. Also, the gas TANK should be ok, as in tank itself.. as long as it doesnt have a pinhole leak (no way to make pressure) and the fuel pump isnt "Buzzing" at you when its driving, indicating 1) Imminent failure, or 2) Pressure issue (too high or too low.)
Ive never really had a car "fixed" by changing a Filter.. maybe it accelerated smoother, but never "Wont start" to "Will start." Hope that helps.
2) As to "Fouling Spark Plugs?" .. Good spark plugs look dirty, same shape as original, and no messed up electrode. Properly heat ranged plugs should pose no problem. And getting more power to the spark plugs, with a simple spark plus (bigger wires, more powerful coil, MSD?) does more than crazy fancy plugs that are WRONG for the car.
The Injectors MIGHT need professionally (Taken out and cleaned) if the Redline S1 wont clean them. Then again, there is debate on that too.
If you can not use the car for a week (park it somewhere,) Injector-Rx can get them to good as new, and if it IS defective (Can mimic a lot of other issues, from clogged Fuel Filter to blown Head Gasket if an injector isnt working right or having issue, stumbling, hesitation, etc) they can tell you that too. It is either "Comes back as new, or "Sorry IRX could not clean this injector it was found to be defective, needs replaced. Here are your other three, five, etc.)
What is your Mitsubishi doing now?
Other mechanics will chime in too im not expert, sharing my experiences.
I also had a vapor-locked car (that ran out of gas at the gas station) start after removing the Oil cap. Then it started right up after running out of gas, as opposed to turn, turn, turn, crank, crank, crank.. almost start, push gas pedal, die. No idea on how that happened.
