This review is from: Stant 10591 Locking Fuel Cap (Misc.)
It was easy to pick the right cap for my GMC 2500HD truck. The cap came quickly and fit correctly the first time I used it. This product won't stop someone from putting a screwdriver thru your tank bottom, but it will discourage someone from a quick syphon from your tank. Mine is full of diesel !
