Radium Engineering Fuel Hanger | 1993-1998 Toyota Supra (20-1510 / 20-1511 / 20-1512)

The MK4's fuel delivery legend starts in the tank with a hanger built for three pumps.

The Radium Engineering Fuel Hanger for the 1993-1998 Toyota Supra is the drop-in foundation: replacing the JZA80's factory pump assembly with a hanger that accommodates up to three fuel pumps, including brushless pumps, with an integrated venturi jet pump for fuel scavenging keeping the pickup fed while the chassis works. No permanent fuel access cover modification is required. Anodized aluminum construction, high current electrical hardware, and gasoline, E85, and methanol compliance throughout. Pumps sold separately.

The Details

The Supra's power ceiling has always been fuel-limited before it was turbo-limited, and the triple-pump architecture answers every chapter of a build's life: one pump for the street phase, staging added as boost grows, and brushless capacity when the dyno numbers get serious. The redesigned siphon eliminates restriction on the return line while still scavenging effectively, which means higher flowing pumps can be used without inducing fuel pressure issues. Mixed brushed and brushless strategies are possible on the 20-1511 by combining an E5LM with GSS342 or AEM pumps. Wiring pairs a Radium DIY kit per pump, brushless pumps add their controllers, and the 20-0415 plumbing kits carry the delivery onward through the JZA80-specific filter mount to the 2JZ rail.
