    I need to drop my gas tank to do a shackle flip. Problem is the day before i blew up my 10 bolt I got gas. So I have about 25 gallons of gas in the tank. I can't get it out. I have tried to shove a siphon hose down the filler tube, but I can't get it down there b/c of the shape of the filler tube (curves). I have also thought about un doing line @ the fuel filter, turning on truck and letting the fuel pump run. But I heard that is VERY dangerous. Please help, I need to get rid of this gas. No I can't drive the truck, I pulled the rear axle today, which was dead. Thanks!

    Try putting a coat hanger in the hose to help shove it down...for some reason this worked for me when I had to check the level...if you get the siphon hose down there, be sure to blow air through it before you suck...I forgot and had a headache for a few days.

    When my fuel pump died (completely dead) I had 3/4 of a tank.
    Take the time to build a cradle for your floor jack that completely supports the tank. It can be done.
    My job sucked even more - the splash bucket in my tank was shattered so I needed to replace the tank. What a mess.

    Sorry Chad, nothing personal but that's not at all safe. Deleted the post and a reply below. Again nothing personal but your idea is VERY unsafe.<P ID="edit"><FONT SIZE=-1>Edited by Grim-Reaper on 05/28/01 05:34 PM (server time).</FONT></P>

    Uhh that's a pretty BAD IDEA to use a vacume and a real quick way to blow yourself up. Even if the fuel doesn't make it into the vac the fumes that are the real danger will and electric brush motors do spark and you have effectivly created a vacume cleaner bomb. A shop vac sould never beused to pick up ANY flamable liquid. I think that is even stated in the instuction manual.
    Hit K-Mart and pick or a boat Fuel line with a primer bulb. Usualy the you need to flip the bulb around because the long hose is on the wrong end. You can make a few pumps and as long as your draining to a lower point it will syphon. I zip tie and a coat hanger to the end to help get it to the bottom of the tank.
