Losi LOS4141 Gas Tank Cap Set

This gas tank cap set is a direct factory replacement designed for all 5IVE-GAS-based Losi models, including the 5IVE-T 3.0 platform. Molded from durable composite material, the set includes the tank cap along with the internal gas seals needed for a secure, leak-resistant fit. A properly sealed fuel cap is essential on gas-powered 1/5-scale trucks, preventing fuel evaporation, contamination, and spills during transport or hard running, while also maintaining consistent tank pressure for reliable engine performance. Over time, seals can harden, crack, or lose their grip from heat and fuel exposure, making replacement a routine maintenance item for active gas-powered fleets. This set restores factory-correct sealing and fitment without needing to source aftermarket substitutes that may not match the tank opening precisely. The composite construction resists fuel-related degradation better than lower-grade plastics, extending service life under repeated fueling and field use. Includes one complete gas tank cap set with all seals, ready to install as a full replacement for a worn or damaged original unit on any compatible 5IVE-GAS chassis.
