Product details

Description

Six parts that each solve one specific problem in a fuel or induction system.

A group of Radium Engineering specialty components spanning fuel delivery, oiling, and induction, each addressing a distinct application.

Choose Your Part

  • Fuel pulse damper kit, MK4 Supra (20-1389)
  • Baffled oil cap VTE kit, GM (20-0587)
  • Fuel tank lock ring, C8 Corvette (20-1115)
  • Venturi jet pump kit (20-0180)
  • FPD-R 8AN ORB (20-0776)
  • Distribution block, 12-10-10-10 with fittings (20-0737)

What You'll Feel

  • Stable rail pressure on a Supra with the vehicle specific damper kit
  • Fuel drawn from the far side of a saddle tank by the venturi jet pump
  • One feed split cleanly to three outlets through the distribution block

Features

  • Vehicle specific and universal components
  • Billet aluminum construction, anodized
  • Stainless steel hardware
  • Fuel and ethanol compatible where applicable

The Details

The 20-0180 venturi jet pump is the part that makes saddle tanks workable: it uses returning fuel flow to draw fuel from the opposite side of the tank across the saddle, which is how a factory system keeps both halves usable without a second pump.

The 20-0737 distribution block takes a 12AN feed and splits it to three 10AN outlets, which suits multi-rail or multi-circuit systems that would otherwise need a stack of tee fittings.

The 20-0776 FPD-R is the 8AN ORB standard range pulse damper, covering 40 to 70psi base static pressure. Like all dampers it cannot be used with mechanical fuel pumps or direct injection high pressure pumps, which will rupture the diaphragm.

Kit Includes

  • Selected component with its mounting and sealing hardware

Applications

Important Notes

  • The FPD-R cannot be used with mechanical fuel pumps or direct injection
  • FPD-R base static pressure range is 40 to 70psi; use the FPD-XR above that
