I thought that without pressure in the system, gas would not pour out.
Well, stupid me. I got a face full of gas and had to tighten it while it was
running out.

Can you, or anyone, tell me if the entire tank will drain if I take these
fitting apart? I tightened them back up till I read through the FSM to
figure it out.

Is this the gas that is in the line? Or the gas that is in the tank?

It is both. Consider how a siphon works - after you swallow two or three
mouthfuls to get it started, a siphon requires no further assistance to
maintain the flow up out of a tank as long as the outlet is lower than the
fuel level in the tank.

Some possible solutions:
- Drain the tank with a siphon
- Elevate the front of the vehicle relative to the rear
- Open the line at the top of the tank so that a partial vacuum
can not be created.
