How do you

[busser]

get ALL of the gas out of a standard gas tank? TIA Busser

[Red Diamond]

Pull the petcock.

[Smokinjoe-VRCCDS#0005]

Take it off and dump it out ....Excellent time to service the air filter.

[busser]

I've taken out the petcock, turned the tank upside down, side ways, right side up, and still there is gas in the tank. Is there a baffle inside? TIA Buss

Guess you could light a match and stick it in the tank to see where that gas is staying at....JUST KIDDING!!!!

Do you have access to compressed air?   Hang it up with open holes, it will evaporate eventually.

[John U.]

Acetone will clean out sludge and the remainder will evaporate quickly. Keep it off paint.

I got a large syringe with a 24" rubber tube, stand the tank on end, and suck the fuel out.   I do this every year, and still am amazed at the crap I find in the bottom!!

You can get a large syringe from Wal-Greens, or any pharmacy.  Rubber tubing from any auto store......  I have done this with the tank on the cycle, but I still feel that having the tank off the bike, and standing on one end so all the fuel goes to one corner is the easiest.

Thanks!!! That was what I was looking for. I support your "world peace" solution. Busser

Drilling 10 - 15  1/4" holes in the lower areas of the tank might do the trick also...

Drive as far from a gas station as you can. You will empty your tank.

I do the same - and use a length of surgical tubing - neoprene - to fish into the bottom corner and siphon the last out.  I also have a suction device that will suck on a hose when it's hooked up to compressed air - use that while wiggling the hose in the tank to collect what might be missed while siphoning.  Then put in a piece of durable, absorbent paper toweling - the kind that holds together meant for reuse - wad it up, put it in the tank to absorb what remains - and of course, remove the wad.  Then if I need it to be vapor free - put a hose in it hooked to my low-pressure regulator I use for airing my powdercoater - regulated at 10 lbs.  Let that blow air into the bottom of the tank for 10 minutes.  After that - I can't even smell gas in the tank. At this point, I'm ready to weld on the tank.  But I still wait a while for more airing out.  Superstitious probably.
