What I like about the Home DIY gas station I'm building is that it can be
extended to a 55-gallon epoxy-lined drum, if I can get one on the cheap.

 The problem with steel is it rusts.
The problem with plastic is static.

You can see the fuel level with a poly tank.  Not so with steel.
You're right about rust.  The tanks will need to breathe and each inhale due to temp changes or pumping fuel will add moisture to the inside. Gas with alcohol (E10 to E85) contains water.  The E fuel can absorb some water vapor but once it reaches the max then it will drop out as water.  The only way to stop internal rust on a steel tank is with lining (epoxy, etc).  You can paint the outsides of a drum.  Keep it off the ground.  E fuel also attracts algae that grows at the fuel water interface and on the inside tank walls above the fuel level where there is moisture.  This is a very big issue with petroleum based fuels. Algae lives in the water and eats petroleum.  Many commercial and industrial fuel stations have their tanks cleaned every year or two. Tank cleaning is expensive... 4 to 5 digits.
I suggest adding a small fuel filter assembly at the pump outlet.
10 micron hydrosorb will keep the dirt, water, and algae out of your vehicles.  Keep a spare filter handy.
