![]() ![]() The OEM VR38DETT fuel pulse damper can be reused with this adapter. These can install into any fuel rail port provided there is adequate clearance. Two Radium fuel pulse dampers and a pressure gauge are included and all necessary adapter fittings. PTFE fuel lines run from the FPR to the rear fuel rail ports. Low profile 90 degree SAE adapters with PTFE fuel hoses connect the OEM hard fuel lines to the FPR. ![]() When used with the 20-0556-02 fuel rails, this kit permits a bolt-on, plug and play affair.Ī stainless steel mount if provided for the Radium FPR. NO FITTINGS ARE INCLUDED.Ģ0-0556-PK Fuel Rail Plumbing, Nissan R35 GT-R There is also opportunity to plumb the fuel rails in parallel or series.Īs shown below, the base kit (P/N: 20-0556-02) includes ONLY the fuel rails and associated mounting hardware. ![]() With 4 ports on each rail (8 total), it is easy to add fuel system accessories such as a pressure transducer, fuel pulse dampers, etc. Additionally, the OEM injector clips can be reused, as shown below. The unique lower intake manifold mounting points permit shorter less restrictive rails. The fuel rails mount with insulating spacers and washers for 100% fuel insulation from the hot intake manifold. The fuel rail features 14mm injector bores and is compatible with the OEM injectors and any aftermarket injectors with OEM VR38DETT fitment. Each rail has four 8AN ORB ports (2 end ports and 2 top ports for a total of 8 ports). They are machined from 6061 aluminium and anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. These Radium Engineering fuel rails are compatible with the VR38DETT engine found in the Nissan R35 GT-R.

Like any fuel system part, the FPD kit should be kept away from excessive heat areas. For best results, the damper should be plumbed as close to the fuel rail(s) as possible. Using the supplied M6 bolts/nuts, the FPD kit can be mounted at any possible angle including upside down. These fittings seal to the billet housing using Viton O-rings. Depending on the size of the fuel feed hose used, there are 3 kits to choose from which include different male adapter fittings (-6AN, -8AN, -10AN). The kit features an anodized aluminum housing with a large 0.69" center bore that uses two in-line inlet/outlet ports that are machined with 3/4"-16 UNF threads for 8AN ORB fittings. Any dynamic fuel pressure created by a rising-rate FPR outside of this range is acceptable, but only when the base "static" fuel pressure is set within these ranges and the vacuum/boost reference line is hooked up. ![]() IMPORTANT: The ranges above are base static fuel pressures only. The FPD- R (Fuel Pulse Damper- Range) and FPD- XR (Fuel Pulse Damper- Extra Range) both have unique base "static" fuel pressure requirements:įPD-R base pressure requirement = 40 - 70psi (static)įPD-XR base pressure requirement = 40 - 120psi (static)īase pressure is the fuel pressure measured when the fuel pump is running WITHOUT a vacuum line connected to the regulator. The FPD-R (green top) is slightly shorter than the FPD-XR (black top) allowing it to be used in space-contrained applications. What is the difference between FPD-R and FPD-XR? This becomes essential for boosted systems that use a 1:1 rising rate fuel pressure regulator. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out.Īlong with having the flexibilty of using common fittings, Radium Engineering FPD's use a vacuum/boost reference port which allows for proper fuel pulse damper performance even at elevated fuel pressures. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. The opening and closing of fuel injectors creates pressure pulses in the fuel rail which can lead to unstable fuel pressure. ![]()
