 This is another example (following the exhaust fans on the engine screen 
setup which still makes me crazy) of attempting to be clever and getting TOO 
clever.

Chris. You hooked up the vent hose (which is supposed to just vent) to the 
air cleaner which SUCKS!!!!!!   So, you step on the gas, the engine sucks air, 
creates a vacuum in the line that has a check valve in it, and sucks it closed. 
  Now you are sucking on the tank from two places--the fuel pump, and the 
'vent' which isn't.   You're lucky you didn't do more damage.

Just vent the fuel tank to the ground, and consider yourself extremely 
fortunate that the tank is so strong due to its irregular shape. 

And, two thumbs up for DRIVING the car in conditions that would keep many 
other Panteras locked away in the garage. :>)
