Short notice help ! Moving and need to drain gas tank!

[Ponyperformance8]

Moving tomorrow and just found out I have to have an empty gas tank, how hard is it to drain gas on this beast ? Am I better off just trying to ride out the last Gallon ?

I think it would near impossible to drain without major dissassembly but I've used a length of 1/4" vinyl hose to siphon out most of a tank.

You can get a siphon pump at some place like Wal-Mart. They are extremely cheap!

Siphon might be the easiest way to get the most of it out. After that you could run it until it stalls. On bikes where the fuel rail is accessible you can remove one of the injectors and pipe it to a container. I don't have my shop manual handy, but often there is a fuel pressure test port where you test fuel pressure that can be tapped with a hose.

Have you tried this way ?

That is a Harley, and it requires different procedure. Drain all the gas into the oil tank. Let the harley set a few minutes, it will all leak out onto the ground.

After you siphon out most of fuel, try this:

Syphon

Self starting priming syphon ... very inexpensive at a home depot, lowes, or walmart. http://www.homedepot.com/p/DuraHeat-Plastic-Siphon-Pump-DH-10/100372238 @2.95

Thanks for all the fast replies everyone. I'm gonna ride first (my preferred method) then siphon the rest using a siphon borrowed from a friend it'll have to work!

At work, we have a cheap and cheerful external fuel pump meant for a car, hooked up with a positive and negative alligator clamp pigtail, and inlet/outlet fuel hoses attached to it. When syphoning needed, we just hook it up to a 12v battery (either in the vehicle needing the drain, or a portable power pack)

I think it cost $10.00 at the wrecker, and have used it since the late 90's without fail.

I have often eyed this as a potential emergency back up method in case the in-tank pump on a bike of mine failed out in the boonies, but so far have been too lazy to find the closest psi/gph pump, and the appropriate quick release fitting to match the bike's.

I might one day still do it, but I've never had a fuel pump fail, so I'm slacking...

Could you maybe expand on this a little bit? I'm not sure I completely understand. Do you have it hooked to a hose that goes through the filler neck or do you hook it to the fuel line of the bike?

It would have the inlet hose into the tank via the filler, yes, and the outlet plugged into the quick disconnect fitting leading to the throttle body already on the bike, that the OEM tank line goes to.

Just as a last ditch get back to civilization kinda thing, of course. Similar to having a gas can tied to the hood of your car with a hose going down to the carb, when the fuel pump goes AWOL in the bush lol
