The fuel tank cap part of the vehicles is normally made of lock or keyed plastic-like material and provides only open and close duty.  Due to this simple cover arrangement, fuel can be pulled out with any kind of abuse and theft intervention.  With our DEPOKIT Fuel Security products and applications, we install a specially designed device that allows fuel to enter the entrance of the cap but prevents it from withdrawing.  The product has a strainer and resistant to external impacts physical structure where materials such as hoses do not enter.  It is a special technological product that prevents the access of the driver or the user and does not cause any flow loss in fuel purchases.
