How to siphon gas from our tanks

Does anybody know how to get the gas out of the tanks on these trucks?
A siphoning kit doesn't work cause of the rollover thing in tanks now-a-days i think?

I have an 01 4.7 4x4 club cab

Thanks

Drill a hole in the tank??? Why do you need to siphon it anyway?

A brake line behind the gas tank burst, need it out of the way.

Can't do that, I've tried with a siphoning kit and a hose, it gets stuck where apparently new tanks have some rollover thing in them so if a truck rolls gas doesn't spill out.

Isn't it pretty easy to take the box off?
I'd rather than than pull the tank.

Garage
If its a rear brake line he must drop the tank to get to it. I have to do the same thing to remove my brake lines. I'll also, be siphoning gas out of the tank. But I've never heard of this rollover thing, maybe its something new?

OK Cool.
I'm unfamiliar with the setup on these.
My preference would be to support tank and move it over a bit to access that area rather than laying under it on stands, disconnecting everything and pulling tank out only to have to fight it back in place.
A good time to do a clean up , maybe spray some rustoleum and check shocks,flex lines etc..
2 different approaches with the same result ...lol

I don't know I found it in a search and i can't get my siphon tube past a certain point so it must be there but please tell me I'm wrong.

And yeah its right in the middle of my brake line going to the rear conveniently tucked away behind the gas tank.

Don't all somewhat modern cars have anti siphoning protection on tanks?

Sorry I don't know where in the forum it is, but one day I came across a post with a link to the Factory Service Manual in .pdf form and downloaded it. I'm doing the tank removal on a Quad Cab tomorrow to replace a fuel pump and it looks like I'll need to remove a cross member that's riveted in, gonna be fun removing those...reg cab looks easy. Anyway, search for the FSM, download it and good luck.

Hold on! Found it.

This is the one I'm using. Thanks to viperkota.

Yeah i have the fsm and im trying to do it without removing the cross member i don't see why its in the way so I'm ignoring it for now, maybe thats a bad idea though.
Let me know how it goes for you man and how you end up getting the gas out.

Do you have a Quad cab? I don't know if the reg cabs or club cabs have the crossmember... I plan on drilling or cutting out the rivets.
As for getting the gas out...the FSM mentions (I'm paraphrasing here) to use the port on the fuel rail with a hose attached going into an approved container and then letting the fuel pump do the work. So far I just waited until the 'low gas' dash light came on and I have a motorcycle lift I plan on using to lower the tank.
I'll post what happens.

the easiest way to siphon the tank is to remove the bed then pull out the fuel pump cause there is an antisiphon ball in the tank or the fuel rail is a good way also

Yeah i have the quad cab and i think a 2 piece drive shaft too (is it considered two pieces if theres a really short one from the tcase to the big drive shaft?) but when i was down there all day yesterday I didn't see any reason why the FSM says to remove the crossmember or the drive shaft.

How do you let the fuel pump work though is my second question because my haynes said to remove the fuel pump relay before this, i know i can put it back in, but i also read that you need a DRB scan tool otherwise operating the pump like this could be really bad.

My 95 Dakota 'had' the ball....is it an anti siphon device or roll over anti spill device? I use my 95 as a 'reserve' tank whenever we have a storm in the Gulf. Last hurricane my electricity was off for several days and instead of keeping several cans of gas stored in my garage for my generator, I just use the truck for that and then whatever I don't need gets used up when I drive it.
