Description
Suits:
- Mazda RX-7 FD3S
The OEM fuel filter on the FD3S is notoriously difficult to service. The Radium Engineering Fuel Filter Mount relocates the fuel filter to an easily accessible position on the rear subframe, where it benefits from natural cool airflow in that area. The mount features integrated cooling fins that help dissipate heat generated by high-current, high-pressure fuel pump setups — keeping fuel temperatures in check under demanding conditions.
This is a custom setup mount — a Radium fuel filter, 10AN ORB fittings, and fuel feed hose must be purchased separately.
Plumbing Notes
90-degree fittings are required on both ends of the filter. The following fittings are shown in the reference image for a typical aftermarket setup:
- 20-1000-1008 — 10AN ORB Swivel Banjo to 8AN Male (qty: 2)
- 14-0207 — PushLok Hose End, 8AN, 45° (qty: 2)
Kit Includes
- Anodised and laser engraved finned heat exchanger
- Anodised aluminium FD RX-7 specific filter mount
- Stainless steel hardware
Required (sold separately)
