This system is used in vehicles with multiple fuel tanks to control and balance fuel flow, allowing manual or automatic switching between tanks.

Fuel thefts can occasionally occur from this system as well.

Fuel Guard provides security solutions for valves and taps between dual tanks. Special fittings and corresponding serial numbered seals are used for each valve and tap. In cases requiring repair or replacement, the serial numbered seal is broken, and the fitting is removed. After the repair or maintenance is completed, the protective fitting and seal are reinstalled.
