Exclamation MAF sensor trouble (Mass air flow sensor)

so my friend has a 1986 Mercedes 420, so i got it running from sitting for a few years, that was about 7 months ago, and now we where going to get it going again, so we hooked up a battery and then we turned it over, the gas gage was empty so we filled it up with a few jerry cans, then we tried it again, he said just dump some gas right in carb to prime it, im like ok, i looks to be a carbonated engine, it is old and i dont see injector lines, knowing that if you prime a fuel injected engine that it will mess up the MAF sensor, so we primed it and then it ran for a bit and studderd and died, dump more gass in there, i would start run of a few seconds and die, so it is only running off the gas we pour in there, it is not getting fuel, but even if the tank was dry we would of bled of all the air in the lines so we would get fuel to the engine by now, right, so it dawned on me, so i was like wtf, i took of the air filter housing and there is a injector lines and injector stuff, i dont know anything about fuel injected stuff, so im guessing i got the mass air flow sensor wet, and its not letting fuel in, so how do i clean the MAF senor and where is it, i can pick up some MAF senor cleaner,
