My gas is disappearing all of a sudden.. I don't have a check engine light ... Any idea what could be causing this???

 

This may sound stupid but were do you park it. I was going crazy and the guy next door said he saw some low life around. I stuck a small piece of paper in my gas fill cover and next day it was on the ground. Locking gas cap. Just a thought.

 

You cant get a siphon hose down a stock filler pipe on my 99. Could drain by opening filter quick disconnect.
