Am thinking of using a auto electric fuel pump for portable gasoline
transfer.

Did some searching and seems workable.

Question: normally an auto electric fuel pumps run from a relay
circuit. Am wondering if the fuel pump can be run directly (no relay)
from a 12 Volt battery.
Maybe it would be smart to have a correct size fuse in circuit in case
something shorted out. Also add that the pump would be used only for a
few seconds at a time.

All the relay does is switch the pump on without the full current of the
pump having to pass through the ECU or ignition box, whatever controls the
pump. Anything that can be run with a relay will work just fine directly off
the battery. A fuse is always a good idea, I'm not sure about the safety of
the whole setup though, gasoline vapors are explosive, personally I'd pump
it with a rubber hand bulb rather than mess with electricity around it.
