Product Description
Stant locking gas caps are OEM quality both in construction and materials as well as deterrent to fuel theft and vandalism. A gas/fuel cap performs three very important functions; safety of the vehicle's occupants, fuel economy and reduce emissions. Safety: Without a fuel cap, gasoline vapors will be present around your car at all times. Those vapors can be ignited by a random spark or flame and are very dangerous if you are involved in an accident or rollover. Fuel Economy: According to Sun Oil Company research, a vehicle with a missing or inoperative fuel cap will allow 176 pounds (22 gallons) of gasoline to evaporate over the period of one year. Emissions: Gasoline vapors emit hydrocarbons which dissolve the earth's ozone layer and cause smog.

Works perfect. THEN BROKE!
By Jettywolf
Locking Diesel fuel cap, priced right and availible.
Take and drill a small hole in this cap and then take no locking cap and pull off the lanyard, and pop it into the hole you just drilled.
No one would know it isn't an exact factory match.
Perfect for the person who'd thinking one step ahead of thieves. Fuel's expensive, I got this just incase. Because you never know when you park all day in a public lot, what's going on.
IT BROKE.......this review has been edited by me. The whole lock mechanism came out and I can still make it work. But GO FIND a metal one (if you can) plastic is crap. Always has been. And if ya have a good grip you could probably spin and break this gas cap anyhow.

Works great.
By J. Cole
This cap fits great and works great. I drilled a small hole on the slanted ridge of the handle and attached my gas cap cord. Yeah, its an extra step when its time to fill-up, but with the price of diesel and a having a 34 gal tank, the extra step is worth it to deter someone from sucking $135 of gas out of my truck.
