Flush Mount Cap Only

The RCI Flush Mount Cap Only (model 7031A) is a replacement filler cap specifically designed for fuel cell systems that require a 3-inch inner diameter twist-on connection. This cap is ideal for those looking to upgrade or replace their existing fuel cell caps, ensuring a secure and flush-mounted profile.

Constructed from durable plastic, the 7031A cap is built to withstand fuel contact and environmental exposure while maintaining a low-profile aesthetic. The twist-on mechanism allows for quick-access refueling without the need for complex fasteners, and the circular filler plate design ensures consistent sealing during operation.

This cap is essential for fuel cell owners performing maintenance or completing custom fuel tank installations. It is particularly beneficial for racing teams and off-road builders who require reliable and functional components in their fuel systems.
