Description

The FHST moves serious fuel out of the FD's tank; this kit filters and delivers it.

The Radium Engineering Fuel Hanger Surge Tank Feed Kit for the Mazda RX-7 FD is the plumbing companion to Radium's FD FHST: the feed-side components connecting the surge tank's outlet toward the engine, built around an integrated Radium high-flow fuel filter with a stainless steel element. This 20-0455-03 version carries a cleanable, reusable stainless element that services for the life of the car, filtering post-pump where injector and rotary-apex protection actually happens.

What You'll Feel

  • The feed side completed with components matched to the FHST, not adapted to it
  • Injector-grade filtration built into the delivery path
  • Serviceable filtration, with replacement elements available rather than throwaway inline filters
  • A cleaner install than piecing hose, filter, and fittings separately

Features

  • Feed-side plumbing kit for the Radium FD RX-7 fuel hanger surge tank (sold separately)
  • Integrated Radium high-flow fuel filter with stainless steel element (20-0455-03)
  • Serviceable filter housing; replacement elements available separately
  • Compatible with all fuel types including E85

The Details

Media choice follows Radium's standard logic: stainless steel elements clean and reuse for the life of the car, suiting owners who service on schedule, while microglass captures finer particles for maximum injector protection and gets replaced at end of life. Position matters too, and this kit filters after the pumps, exactly where fine filtration belongs, with the pump inlets protected separately by their socks inside the FHST. Pair the feed kit with the FHST version matching your pump family, wire each pump properly, and the FD's fuel system finally matches its chassis. Surge tank sold separately.
