Fuel injection system drain down

[poiu]

When laying up my carburetor engine for even a month or so, I used to drain the carbs down. That was a process recommended in the owner's manual and is generally considered a good thing to do to prevent carb glazing, float sticking and needle clogging. Now I have a fuel injected engine and there is no recommendation to do drain down the fuel system, and no instruction how to do it. I viewed a few YouTube engine maintenance videos by mechanics and no one mentions it.

Is it a good idea to do it or does it really matter?
