of the hand siphon type pump that is commonly used.

I'd be concerned about this being a possible source of combustion....

Before you buy.

Yes, and they work well. However most can't be reversed. A deciding factor
is the cost. You can find thrm used at auto salvage yards for around $5-$10.
Hobby Lobby also carries two electric pumps for gas, both around $35-$40.

Jim.....DUH. :) It's an automotive pump and sealed for gas use. There's one
on your car. I've used an electric pump from Hobby Lobby for 3 years and nary
a problem. The battery is a gel cell and sealed in a plastic case. The switch
is an "enviromental" switch, also sealed.

gas, cost about $20.00 and are actually the window washer pump used in
BMW's.

rather completely open armature, brushes and all. The fact that it is
completely immersed, is the reason there can be no sparks. Its the
fumes of gasoline which is dangerous and not in its liquid state.

Jim -
Most if not all current fuel injection-based auto engines use two
electric pumps, one low pressure pump mounted inside the fuel
tank, and a high (relatively speaking) pressure pump mounted
somewhere between the tank and the engine. Both pumps
have a higher delivery volume than the engine can possibly
use, and the excess fuel is recirculated back to the tank. The
excess fuel also serves to cool the injectors (electric solenoid
valves, essentially).
Another class of pump is available from auto parts houses, and
it is the sort that is intended to replace the mechanical engine-
driven pumps. It is an in-line pump, and runs on 12vdc.
About twenty bucks US.
Perfectly safe.
The only problem is the output pressure of these pumps can reach
as much as 10 PSIG, about ten times what your model fuel system
can tolerate. If you add a fuel pressure regulator to the pump's
output, you can dial that pressure down as needed. No worry
about a high-pressure stream of gasoline being squirted about
the pits, should a disconnect occur while fueling.
Use 'em all the time. No worries.

And, you don't generally get gas on your hands and the grass under your
feet while operating your car....
No thanks, I'll stick to my six-shooter....

radically different. Can't remember the last time I got gas on my hands
while operating a vehicle......
As I said in my other reply, I'll stick to my spark free six-shooter,
thanks....

ended up deciding on a Hobby Shack rotary hand pump instead. It's much
lighter--I just clip it to the jug handle--and I don't have to charge
it. Also, it's about the same speed. I'm thinking of replacing my
electric glow fuel pump with one too so I can get rid of my flight box
all together.
