The discussion about removing motor oil made think of this.

What's the best way to pump a large quantity of fuel (gas / oil mix) out of
a built in tank. The tanks are about 25 gallons each and I want to pump them
completely dry into 5 gallon cans.

I have a siphon and know how to use it, but it is difficult to impossible
for this.

In the past, I've used a cheap, little plunger-type hand pump with a tube
going down into the tank and another tube going to the 5 gallon tank. This
worked OK - but not really well. The pump was pretty small and therefore
took way too many pumps per gallon, and the handle was just a little knob
and therefore difficult and tiring to use.

So, I'm looking for a better solution for moving 25 gallons of gas from a
built in tank to 5 gallon cans if anyone has any ideas. An electric
solution or a larger capacity hand pump with a good size handle would be OK.

If I were to rig up an electric fuel pump, exactly how would I do that?
And, what is a typical pumping rate for this?

Many thanks in advance.
