F.A.Q’s




Is the Fuel Safe sold individually?

Yes. The Fuel Safe® is offered as a single unit since not all trucks come with dual tanks, like vocational trucks. If you possess dual fuel tanks, you’ll need to purchase two.

No. The main cap has a set screw and the secondary cap has a key way for added security.


The Fuel Safe is compatible with all models of Kenworth and Peterbilt. Additionally, it fits all Freightliner models that use push-n-twist style caps.



No. For your fuel tank to function correctly, ventilation is required to both release and accommodate pressure and vacuum. The Fuel Safe ® does provide any ventilation.
