I'd take an old mechanical pump and reconfigure it as a "flow through" dummy pump...just for looks.
Get a low pressure solenoid type pump, you can hide it inside the frame rail...and there is a special oil pressure switch available from Standard Ignition, which (with or without a light) will shut off the power to the electric fuel pump should the engine stall or be shut off.
That way you can look stock, but continue running your old-timer on the gasahol.

I would suggest not running gas through an old nonfunctional fuel pump. Alcohol will dissolve the diaphragm and either fill the engine with gas or spurt gas out the fuel pump vent creating a big fire hazard.
