The Edelbrock adjustable return‑style E‑Street EFI fuel kit (part 3604) provides a complete high‑pressure EFI solution excluding the fuel tank. It includes a 67 GPH pump, adjustable regulator (35–90 PSI), filter, Russell Twist‑Lok hose and fittings, mounting brackets and hardware to complete the return loop. The system is rated for engines up to 600 hp when used with an Edelbrock EFI system; a baffled tank is recommended to avoid starvation.
