The TankSafe Fuel Security and Safety Range
The ONLY Device to completely stop any siphoning, skimming and diesel spills
The float-valve prevents skimming or siphoning of ANY fuel from the tank – even small amounts that may go unnoticed by fuel monitoring systems.
During filling, the pressure of fuel flowing in pushes the float ball down to allow fuel to enter the tank.
However, when you have finished filling, the float ball is pushed up and prevents siphoning of any diesel.
The MOST effective anti-siphon at preventing 3rd party theft
Effective in preventing siphoning.
However, if you fill to the top, a thief could still potentially skim some of the fuel from the tank (i.e. to the depth of the anti-siphon).
This type of anti-siphon device prevents theft but DOES NOT PREVENT SKIMMING on a regular basis of small amounts of diesel.
