Probably not worry about it. But if you want to drain..
Here's a trick, unhook the hose from the filter, put a section of 3/8 hose over the flare, then turn the ignition on... unplug the MAP sensor.. jump its gray and green terminals.. that will run your pump and drain the tank. Then go and run straight water through it like a gallon.. shut it down, forget about it.
That will flush all the alcohol out. And the little water left will evap.
Might as well take the filter apart and give it a spring cleaning.
Not much else to do.
