MX-5 / Miata ND RF MK4 Fuel Tank Top Hat - Fuel Return System

Overview

Aluminium fuel tank top hat for the Mazda MX-5 / Miata ND and RF (Mk4), fitting all model years from 2015. It replaces the factory plastic top section while keeping the original pump basket, for engine swaps, motorsport and custom return-style fuel systems with aftermarket pumps, external regulators and dedicated feed and return lines.

The standard ND / RF Skyactiv-G engine uses high-pressure direct injection, so this is not intended to convert the standard engine to a return-style system – it's ideal for port-injection engine conversions and other builds that no longer use the original fuel system.

Unlike the NC and RX-8, the ND / RF pump basket uses steel support rods pressed into the plastic top hat, so we include stainless replacement rods designed for our top hat. Laser-cut aluminium, finished in Performance Delta green anodising and made in the UK. Use the parts picker to add extras and build your fuel system.
