Project DBA R35 Nissan GT-R Bolt On Power Mods Part 2, Fueling for 1000 Hp

For our primary fuel pump, we used an AEM’s 340LPH E85-Compatible High Flow In-Tank Fuel Pump.  The AEM pump features robust internal construction that is designed to withstand the low lubricity characteristics of ethanol and methanol fuels, and are tested to work with ethanol fuels up to E100, methanol fuels up to M100, and all types of gasoline. The AEM 340 fuel pump includes a wiring harness, pre-filter, internal fuel hose, clamps, end cap, and rubber buffer sleeve. Every AEM 340 Fuel Pump is tested to flow 340 lph at 40 PSI before it is packaged for sale. The AEM  fuel pump features a compact 39mm diameter that fits into our Radium Engineering hanger perfectly

For our secondary pump, we wanted something that could move a lot of fuel.  We selected a Ti Automotive BKS1000.  This pump can flow a whooping 550 LPH at 40 psi!  The BKS1000 is an efficient screw pump design with positive displacement that is designed for in-tank installation. It uses a brushless motor for precise control of fuel
pressure, lower current draw, reduced heat, and less noise. The brushless controller logic uses a simple power and ground. The pump output is set to a 100% duty cycle for maximum performance. Brushless pumps require a controller and the BKS 1000’s has sealed weather-resistant electronics with 3ft wiring leads. The pump includes a 31-micron inlet filter. The brushless pump can be run with 8 to 18 volts DC, however, the speed of the pump will change accordingly.  The pump is safe for use with E85.  The Radium fuel hanger is designed to easily accommodate both of these pumps.

The first step in the installation of our fuel system is to lay out all of the parts in the Radium Engineering hanger kit.

Here the fuel level sender bracket is assembled to the hanger top.  The top takes the place of the access plate that covers the top of the fuel tank.

Next, the output sides of the fuel pumps are attached to the manifold assembly that contains the check valves that maintain fuel system pressure when the pumps are shut off.  The one-way fill valve for the surge tank is located here too.
