11-3267 - Thermal Arc Gas Drive Welder Replacement Fuel Cap

Genuine Thermal Arc 11-3267 Fuel Tank Cap

The Thermal Arc 11-3267 is a specialized fuel tank cap designed specifically for Thermal Arc gas drive welding generators. As an essential component of the fuel system, this cap is engineered to meet the precise specifications of Thermal Arc's engine-driven equipment. Unlike generic automotive caps, this OEM part features the correct thread pitch and venting requirements necessary to maintain optimal engine performance during long welding operations.

Constructed from high-impact, fuel-resistant materials, the 11-3267 cap is built to withstand the rigorous conditions of industrial job sites. It is resistant to degradation from gasoline, diesel, and prolonged exposure to UV radiation, ensuring a long service life even in outdoor environments. The cap includes a pre-installed sealing gasket that provides a tight, leak-proof closure. This seal is critical for preventing fuel spillage during transport and operation, as well as blocking moisture, dust, and debris from entering the fuel tank—contaminants that can cause significant damage to the engine's carburetor or injection system.

Proper venting is a key feature of this component. The 11-3267 is designed to allow air into the tank as fuel is consumed, preventing vacuum lock that can starve the engine of fuel and cause unexpected shutdowns. Maintaining the integrity of your welder's fuel system with genuine parts like the 11-3267 ensures reliability and safety. This part is compatible with various Thermal Arc engine-driven models, such as the Scout and Predator series (verify specific model compatibility via manual).

For maintenance professionals and equipment managers, using the correct part number 11-3267 eliminates the guesswork of finding a compatible cap at a general hardware store. It ensures that the safety features, such as spill prevention and pressure regulation, function exactly as the manufacturer intended.
