Just a little background about Fuel Sure. Fuel Sure is a fuel cap designed for diesel cars sold from a UK company online. Its purpose is to prevent misfueling of gasoline into a diesel vehicle. The Fuelsure cap can only be removed by placing a diesel nozzle into the cap's top cavity. Since diesel nozzles are larger in diameter, the cap will not unlock if you accidentally grabbed the gasoline nozzle. This is the company's website.

It's a great concept, but the design is flawed. If there is liquid sitting in the release hole, it will leak thru the cap and enters the fuel tank. This could be water after a heavy rain storm or after going thru a car wash as the fuel lid on the car's body is not water tight; or it could be gasoline in my case!
When I first got this cap and installed it, I immediately went to the fuel station and try to insert a gasoline nozzle and see if the cap releases. Well, the cap did not release as design. However, there were some gasoline residual on the tip of the nozzle, which ended up in the caps release hole when I was testing it. There was a puddle of gasoline in the cap and I immediately uninstalled it not knowing if it will leak thru.
I took the cap home and performed a water test where I put water in the release hole and look from the bottom. Watch the video and you will see the result.

I honestly think this product is doing more harm than good. It cost me $60. Very disappointed. If you have this product installed on your car, I highly suggest you remove it. If you are thinking about getting it, don't!
