Best way to empty built in fuel tank
 

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.

Any auto parts store carries electric fuel pumps. Just add a hose to the
inlet and outlet of the pump. Outlet to the 5 gallon cans. Inlet, either
into the tank, or connected to the outlet of the tank. Wire the pump to a
battery. Far enough away that the sparks do not ignite the fumes.

I emptied the 100 gallon tank in my Scout this way before trailering it to
Florida.
Hooked the pump hose up to the boat's inlet hose to the fuel/water filter.

Worked well, but very slow. Electric fuel pumps don't move many gpm.

I pumped the fuel out of a 25 gal tank in my 4-winns with a small
accordion hand pump(from Walmart) much like what you described. However
I let gravity do the work. With the boat on the trailer and the
receiving tank out side on the ground. I attached a long length of
plastic tubing, I picked up at the store, to the pump and put the end
into the 5 gallon can. Once I got the gas flowing, I just let it siphon
out with the help of gravity. It took about 10 minutes to fill the 5
gallan can. Also, I had to pull the floor board and open a top access
panel, since I couldn't get the hose down the gas tank fill tube
properly. I hope this makes sense to you. Good luck!

I've siphoned my 36 gal inboard tank with a small line out the bilge drain
plug. My tank is located aft pretty close to the back of the boat and it
was fairly easy to do.

Depends on the pump. Used to have a rotary motor driven pump. Moved lots
of liquid, and did not burn up if the pump was trying to pump thick stuff.
Spring connected to diaphram. Used them as cooler pumps on my tranny and
differential when I raced cars.

However you pump it, use the existing fuel line by taking it loose at
some point and adapting a fitting so you can hook on. You know this suction
point goes to the bottom of the tank.

Why not just siphon the take dry? Don't have to worry about sparks and
such. Don't need to go buy a pump to use once.

Siphon's an option - but he was responding to my original post where I
mentioned that siphoning was very difficult because of the way the tanks are
set up - getting the 5 gal cans downhill from the built in tanks requires a
pretty long run. So I was looking for an electric or hand pump alternative.

Thanks to everyone for the many suggestions. I'm still looking for a simple
hand pump with a decent capacity that is OK for gasoline - on the gpm
magnitude of a hand bilge pump, for instance. Haven't found it on the web
or locally.

Thanks again.

The length of the run doesn't much matter. And you don't have to
create the siphon action by pulling the liquid through, like with your
mouth! You can simply fill the hose with liquid, hold your thumb over
one end, put the other end in the tank, then go down hill, and take
your thumb off.
