How hard is it to sump the gas tank in the GTS?

Do you have to pull the tank out? If so is it a task to do?

What are some other ways to pull large volume of gas with a return fuel line?

Can you just drop a fuel line in the tank close to the bottom or do you have to fabercate something to pump the fuel up to the top of the tank and then to the aeromotive fuel pump?

Thanks
