    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.

    Hi Gene...

    Personally I'd be scared stiff even thinking about it.

    Pour your gas, use the sparkless method :)

    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.

    If you must use an electric pump, remember to have the switch far, far
    away from the pupmp and the gasoline.!!!!!!

    A few days ago the news from Denver showed that some one was drilling holes
    in bottom of auto gas tanks at airport parking lots. To steal gas. If they
    were using a battery operated drill (which has sparking brushes) they were
    living on luck. WW
