Ok, I talked to my freind Jerry ( Ford tech @ Planet Ford)
He told me that all Ford/Lincoln/Mercury that is OBDII has a saftey valve/screen so gas won't leak out if the auto is on its side or turned over. He told me that you CAN'T syphon gas out of these cars.
I dunno
Like I said, Ive never tried it myself. I sure if you keep fishing the hose in you might make it through...
Im just passing on the knowledge that has been passed on to me. But on the other hand a locking cap will keep ppl from putting sugar in your tank.
contrary to popular belief, sugar in your gas tank will not cause damage. it cannot dissolve in gaoline to form a liquid solution that would solidify in your lines. that's what would **** it up, turning solid in the lines, but it can't dissolve in gas so nothing happens.
