Draining Fuel Tank

I drained my fuel tank today for the overseas move. I was able to siphon off most of the gas leaving the tank mostly empty. I took off the fuel return line to get even more out, but there was still gas left in it after that. I ended up taking the tank off and getting the rest out of the filler neck.

There has to be an easier way to do this...

I kind of doubt it. There is no way to get all the fuel out using the lines. Probably removing the tank at the start would have made life easier.

yeah its a pita to get everything out... one way would be with a vacuum siphon like a mity vac with a large air tight container t'd in the middle

I typically pull the line off that feeds the injectors, then hook up 12v to the pump and let it do most of the work, then remove the tank, place it over a drain pan and remove the pump. PITA yes.. but I don't have all the nifty tools mentioned previously.

You could always ride it dry (the bike that is ).

How long is it in storage for?

I ask as unless it is a long time I'd be more inclined to leave it full with a cup of meths added to the mix. Otherwise unless you poor in some light weight oil and swish it around to coat the insides of the tank I'd be concerned over rust developing in a empty tank.

But I may be wrong about this.

Vacuuming gasoline sound like a Darwinism experiment to me............

I did as suggested above after running fuel low to start. I pulled injector feed line off, put it into a can, turned on the key. Pump does most of the work. You have to repeat becasue the pump only runs a few seconds but as long as fuel is low to start, not too bad.

Then, I blew air through the tank to dry out the residual fuel, outdoors. No electric motors anywhere close to the fumes................

Safety first..........

Bike is going overseas, so tank has to be dry. After I siphoned as much as I could, I ran it till it died. It still left about 1/4 gallon (maybe) in the tank. The fuel return line got about half of that out and removing the tank allowed me to get the rest.

Could be from 1-4 months. What kind of oil should I use, just regular motor oil? Bike will be in a sealed crate, but will travel on a ship.

I thought I read that rusting in these tanks wasn't an issue anymore - something about material it's lined with, or coated or something? Maybe not?

if you are referring to me.. i never said any thing about an electric vacuum... the mity vac is a hand held vacuum used to draw a siphon most of the time. It is commonly used to draw vacuum on brake lines, but could be used to draw a siphon on the gas and then removed letting nature run its course...
