The Radium 20-0878-PK Fuel Rail Plumbing Kit connects the Radium 20-0878 fuel rail on the VW 2.8L 24V VR6, replacing all OEM components downstream of the OEM SAE quick connect hard lines in the engine bay. Using an assortment of PushLok hose ends with EFI hose, the kit can be tailored to any vehicle running the 20-0878 rail.
Fuel pressure is controlled by a high-flowing Radium MPR-RA multi-port regulator, 1:1 vacuum referenced into a dead-head fuel rail, and the supplied 0–100psi gauge makes pressure easy to set and monitor. The EFI hose is compatible with all fuel types including E85, and plugs are included for all unused ports.
