Radium Engineering Fuel Pulse Damper, Direct Mount Kits

Thu, 6 Oct 2022 06:51:12 GMT

Radium Engineering Fuel Pulse Damper, Direct Mount Kits
Buy Now: $89.95

The opening and closing of fuel injectors creates pressure pulses in the fuel rail; this can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out.

Fuel pulse dampers can be mounted at any angle, including upside down. There are many variables that dictate if a fuel system requires fuel pulse dampers. For instance, there are cases where multiple dampers are necessary. There are also other times when the fuel system benefits with a fuel pulse damper on the return line.

NOT TO BE USED ON THE LOW PRESSURE SIDE OF MECHANICAL FUEL PUMPS (INCLUDING DIRECT INJECTION ENGINES).

What makes Radium FPDs unique?

Along 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 becomes essential for boosted systems that use a 1:1 rising rate fuel pressure regulator.

What is the difference between FPD-R and FPD-XR?

The FPD-R (green top) is slightly shorter than the FPD-XR (black top) allowing it to be used in space-contrained applications.

WHICH DAMPER DO I CHOOSE?

The FPD-R (Fuel Pulse Damper-Range) and FPD-XR (Fuel Pulse Damper-Extra Range) both have unique base "static" fuel pressure requirements:

FPD-R base pressure requirement = 40 - 70psi (static)
FPD-XR base pressure requirement = 40 - 105psi (static)

Base pressure is the fuel pressure measured when the fuel pump is running WITHOUT a vacuum line connected to the regulator.

IMPORTANT: The ranges above are base static fuel pressures only. 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 connected.

Example 1:
Vehicle: Mitsubishi EVO
OEM Base Static Fuel Pressure: 43.5psi
Boost Pressure: 30psi
Rising Rate Pressure Regulator? Yes
Can I use a FPD-R? Yes. Even though fuel pressure is 73.5psi at full boost, the FPD-R will work because the base static pressure was set within the 40-70psi requirement. However, the vacuum/boost reference line must be installed.
Can I use a FPD-XR? Yes. Also, the vacuum/boost reference line does not need to be installed since maximum fuel pressure does not exceed 105psi.

Example 2:
Vehicle: BMW E46 M3
OEM Base Static Fuel Pressure: 72.5psi
Boost Pressure: 20psi
Rising Rate Pressure Regulator? Yes
Can I use a FPD-R? No. Base static fuel pressure exceeds the 40-70psi requirement.
Can I use a FPD-XR? Yes. Also, the vacuum/boost reference line does not need to be installed since maximum fuel pressure does not exceed 105psi.

Features
1. The anodized aluminum housing features two selectable threaded male fittings:
a. The 8AN ORB versions seal using a FKM O-ring.
b. The 3/8" NPT variations seal with the tapered pipe threads.

2. Vacuum Port Orientation:
a. Even after tightening, the top port of the newest 8AN ORB fuel pulse dampers (20-0776 and 20-0777), will swivel permiting the vacuum port to be clocked 360 degrees.
b. Because 20-0178 and 20-0179 use tapered threads (NPT), the vacuum port can be clocked to the desired location.

3. This product is safe for use with all fuel types including alcohol blends such as E85.

Radium Engineering Fuel Cell Surge Tank

Wed, 15 Dec 2021 11:30:36 GMT

Radium Engineering Fuel Cell Surge Tank
Buy Now: ~~$749.95~~ $749.95

BACKGROUND

Since 2010, external Radium Engineering fuel surge tanks have been an excellent way to eliminate fuel starvation that occurs in racing. To simplify plumbing and packaging, in 2013 Radium Engineering introduced the first generation Fuel Cell Surge Tank (FCST) to the competition vehicle market. It quickly became the preferred fuel system for professional racing.

WHAT IS A FCST?

The Fuel Cell Surge Tank is a drop-in fuel pump system for Radium Engineering's popular fuel cells or any cell that uses the industry standard 6x10 24-bolt fill plate bolt pattern. The FCST is designed to protect EFI vehicles that experience fuel starvation. It is NOT a glorified trap door box with baffles. It features a true dual-chamber fuel tank utilizing a single lift pump and up to 3 surge tank pumps all packaged inside the fuel cell. It provides all the benefits of a traditional external fuel surge tank without safety concerns and plumbing complexity.

IS THIS COMPATIBLE WITH MY FUEL CELL?

To install a Radium Engineering FCST into a fuel cell, the following criteria must be met:

1. The cell must have the industry standard 6"x10" 24-bolt flange opening.

2. The opening must be on the top face of the fuel cell (i.e. not a side face).

3. The cell depth must be at least 7.7" (196mm) measured from the outer top face to the internal bottom face.

HOW IT WORKS

A lift pump scavenges fuel from the bottom of the fuel cell and pumps it into the 2 liter surge tank. Inside the surge tank canister, up to 3 EFI fuel pumps can be used to feed high pressure fuel to the engine. If the lift pump starves, the volume inside the surge tank canister will keep the surge tank pumps fed and the engine supplied with fuel. The return from the pressure regulator is also routed to the surge tank canister to help keep it full.

There are three fill valves integrated to the bottom of the surge tank. These 1-way FKM fill valves are sealed shut unless the fuel level in the cell rises above the fuel level in the surge tank. If this happens, each fill valve opens and sends 355LPH of fuel (1065LPH total) into the surge tank until fuel level reaches an equilibrium.

Excess fuel in the surge tank simply overflows back into the fuel cell. This dynamic sequence is all done inside the safety of a fuel cell.

FEATURES FOR 20-069X-XX FCST

Over the years, Radium Engineering has continued to refine the FCST into a robust and highly functional piece of hardware.

-Merged single 10AN ORB female threaded outlet. All pumps use check valves that prevent back-flow for multi-pump applications.

-One-way fill valve located on the bottom of the canister that allows fuel in, but not out, keeping the surge tank full.

-Multiple fuel pump options including gerotor, turbine, and brushless DC motor pumps.

-Hermetically sealed high-current stainless steel electrical studs capable of handling all pumps.

-Simplified servicing features eliminating nylon sealing washers and fuel cell retaining brackets.

-Full CNC aluminum construction with anodized surfacing for superior corrosion resistance.

-Fuel compatibility: leaded and unleaded gasoline, methanol, ethanol, E85, etc.

-Dynamic safety vent valve with rollover protection and fuel fill shut-off.

-Optional fuel surge tank level switch and diagnostic LED failsafe port.

WHATS IN THE BOX?

The following comes standard with every FCST variation configured per part number

-8AN DSV (dynamic safety vent) valve

-6x10 24-hole FKM gasket

-6AN male return fitting (other sizes can be utilized)

-8AN male pump out fitting (other sizes can be utilized)

-Fuel level sensor block-off plate

-Fuel level switch block-off plug

-FKM 1-way fill valves

-Stainless steel mounting hardware

-Insulated anodized aluminum acorn nuts

-Electrical power wire ring terminals

-Links for compatible fillers (not included), Direct Mount or Remote Mount

SELECTING YOUR FCST

The different FCST part numbers are based on the brand and quantity of fuel pumps. When determining a fuel pump configuration, use the chart below to select a combination that can support the engine's output.

20-069X-XX FCST

The 20-069X-XX Fuel Cell Surge Tanks (with exception to brushless E5LM) are available with and without pumps included. The lift pump is always matched to be the same style pump(s) found inside the fuel surge tank canister. Any option that lists "Pump Included" comes pre-assembled with new fuel pumps and filters installed.

If "no pumps" are ordered (shown above), fuel pumps must be sourced separately. A filter sock will only be required for the lift pump as inlet filters are already supplied for the surge tank pumps. Also, there will be enough components included with this option to use up to 3 pumps in the surge tank. Depending on the setup, some parts may not be used.

20-0693-00 FCST, PUMPS NOT INCLUDED, BRUSHLESS TI AUTOMOTIVE E5LM

The 20-0693-00 Fuel Cell Surge Tank is only available without pumps included. It is designed to use one or two Ti Automotive E5LM brushess fuel pumps inside the surge tank. A standard brushed pump is used as a lift pump.

As shown below, the lift pump electrical and plumbing is set to be compatible with Walbro F90000267/274/285/295 fuel pumps. Radium Engineering recommends the Walbro F90000295 as a lift pump for maximum flow. Filter socks are required for all pumps.

NOTE: Ti Automotive brushless fuel pumps do not have integrated check valves like many other pumps.

So this FCST includes two 20-0598 fuel pump outlet adapter check valves (shown above). Because the 2 surge tank pumps merge into a single outlet collector, these high flow 1-way valves permit multiple pumps to be staged without backflow.

20-0695-00 FCST, PUMPS NOT INCLUDED, EXTERNAL PUMPS

The 20-0695-00 Fuel Cell Surge Tank is only available without pumps not included. It is designed to be used with a mechanical fuel pump or inline electric pump(s). One or two -10AN (5/8") fuel pickups are used inside the surge tank. Each pickup uses a 80u (micron) filter. If two pickups are used, 20-0737 Distribution Block is recommended for pumps that use a 12AN inlet.

The lift pump electrical and plumbing for this kit is set to be compatible with Walbro F90000267/274/285/295 fuel pumps. Radium Engineering recommends the Walbro F90000295 as a lift pump for maximum flow with a 14-0143 Filter Sock.

STANDARD FITTINGS

PUMP OUT -8AN MALE

The external fuel pump outlet port is signified by the "PUMP OUT" engraving. It uses 7/8"-14 threads making it compatible with all 10AN ORB fittings. The FCST comes standard with a common 10AN ORB to 8AN male adapter fitting.

RETURN -6AN MALE

The external "RETURN" port is used for low pressure fuel returning from the FPR. This port uses 3/4"-16 threads making it compatible with all 8AN ORB fittings. The FCST comes standard with a common 8AN ORB to 6AN male adapter fitting.

VENT -8AN MALE

The external "VENT" port is tapped with 1-1/16"-12 threads making it compatible with all 12AN ORB fittings. The FCST comes standard with 20-0435 which uses a common 8AN male outlet fitting for standard fuel filling. However, 20-0535 can be purchased separately with a 12AN male fitting for quick fill dry break systems that require a high-flow vent.

WHAT ELSE IS NEEDED?

FUEL CELL

A fuel cell is not included with the FCST. The fuel cell MUST use a 6x10, 24-bolt fill plate flange. The distance from the outer top face to the internal botton face must be at least 7.7" (196mm). The distance from the top of the fuel cell to the bottom of the lift pump filter (lowest point of the kit) is adjustable.

VENT HOSE

A hose and/or filter must be connected to the "VENT" port fitting.
