Fuel Caps

In 1980, GT Development introduced the first effective anti-spill tank vent for diesel powered heavy-duty vehicles. Since then, the company has gone on to introduce dozens of innovative fuel system products, many of them patented.

GT Development fuel caps incorporate a unique combination of thermal, venting and pressure relief to protect the fuel system in the event of a fire or a roll over. These devices ensure that diesel fuel is not released prematurely, while minimizing the opportunity for pressure to build-up inside the tank. The safety devices are engineered into rugged, aluminum die-castings that stand up to daily use and abuse. All designs meet or exceed FHWA guidelines for leakage, drop tests and flame tests.

GT Development’s vented fuel tank caps are supplied in a broad variety of 2”, 2.5”, 3”, 3.5” and 4” sizes with integral breather vents and safety venting features. Options include chrome, matching locks, and custom logos. GT also offers closure-only caps which are custom designed for special applications where a separate fuel tank vent is located in the fuel tank.
