Then I sloshed my tank with tank liner (forgot the name, it's the red stuff.) That was a few months ago, and it seems to be working fine.

I also removed the tumbler pins from my gas cap so I can open the tank with a screwdriver. It's 4 gallons. I'm not worried.

4 gallons? In some areas 6.04 is the gas price. The thieves hit ya once, they're likely to try again.
