Draining gas tank on 2013 Horizon H210

caruguy · **Posted:** Sun Jul 12, 2015 10:24 pm

I have a 2013 Horizon H210, I have a close to full tank of gas that is of dubious quality and wish to drain it out. How would I go about doing this. Is there a relatively simple , foolproof way of doing this ? Look forward to hearing from anyone , that may have experienced this problem.

In a very well ventilated area, remove the gas tank inspection cover and use a gravity style siphon hose to drain the fuel.
I've used a garden hose through the bung & while it took hours, it was simple and safe.

Buy an automotive fuel pump and 1/4" fuel hose. This is the safest way to pump without a creating a spark. Make long leads and hook it up direct to a battery.

You can pump direct from the tank like suggested above... The best way to get it all. Or, you can disconnect your fuel line from the fuel filter and install the pump on that line.

We have also added water a separator and a filter to our discharge line to try to salvage the old gas for movers and such.

The way I've done it is to:
1) switch off the batteries
2) lift out the rear bench seats
3) remove the gas tank hatch
4) carefully remove the screws/bolts for the gas tank sending unit and lift it out. Then you will have a nice large opening to use a pump with a large diameter hose. This is how I pumped out gas during superstorm Sandy for our generator.

I'd connect it to an external battery source, as it will cause a spark when you connect the leads to the battery terminals! :wink:

I agree!

How bad is it? Could you treat it, run it and then swap in a new fuel filter?

Before you go through all that, I'd remove the water separating fuel filter and pour out the contents in a large glass jar. Let it sit for a day or so. Then look to see if there is a layer of water on the bottom. If not and the gas doesn't have other debris in it, I'd just use it. If so then you can sometimes pump out the bottom few gallons and after that the gas will be clear. That's a lot of gas to pump out (40+ gallons).
When I did this I had a gas caddy (15 gallons) and 4 five gallon gas cans. Used it all up in the generator during Sandy (2 weeks no electric). I used a hand pump and as soon as I started a siphon the gas came out pretty quick. It works better if you have one person pumping and another person watching the hose in the gas can. BE CAREFUL, its not just electrical sparks that can cause it to ignite, even static electricity sparks can do it. Gas can must be on the ground. NOT on the swim platform.

The external fuel pump and a universal marine fuel line (with primer bulb) will cost you about $80. An excellent investment because I never need to worry about old fuel. I just disconnect the existing fuel line and connect to the external fuel pump and remove fuel. I removed 64.5 gallons from my 65 gallon tank so the fuel line intake is at a really low point in the tank. Opening the fuel tank is dangerous and unless the fuel gauge sender gasket reseals perfectly you have created a vapor leak.

When you remove that sending unit you should replace that gasket.
They don't last forever anyway. Just be REALLY careful about hooking up any electric pumps to pump out gas. The only way I'd do it would be with a remote battery and LONG electrical leads, with a switch.

Drained gas today, 1/2" clear hose, fed up thru transom drain hole. Removed sending unit, fed hose into tank via sending hole. Syphoned off16 gallons. Tank was bone dry. I dont know where the other 24 gallons went. "I guess it evaporated in storage at marina" Wont be storing there again. Thanks for all the member advice.
