Review on Stant 10510D Diesel Locking Fuel by Chris Tisdale

Perfect replacement for the stock gas cap. If someone still wants to get to your filler neck, they will, it will only slow them down. But for a less motivated person, they will just move on to an easier goal. My fear isn't someone stealing my diesel, it's a fear someone will put something other than diesel in my tank, and for that it's a pretty cheap insurance plan, especially considering how much a wrecked truck is going to cost one of them, it's just that someone dumps a cupful of cow urine into the aquarium.
