MX-5 / Miata NC MK3 Fuel Tank Top Hat - Fuel Return System

We will have a limited amount of stock available to ship mid to late June.

Upgrade your MX-5 NC fuel system with our aluminium fuel tank top hat, designed to replace the restrictive factory plastic unit and enable the use of a proper fuel return system.

Perfect for turbocharged, supercharged and high-power applications where stable fuel pressure, improved fuel temperature control and aftermarket fuel system compatibility are essential.

Unlike the OEM dead-head arrangement, this top hat allows excess fuel to circulate back to the tank, helping reduce fuel temperature build-up and improving consistency under prolonged hard driving and track use.
