9/9/2023 0 Comments Radiumauto fuel cell![]() Pressure graphs are commonly published for all popular fuel pumps and if you are unsure, contact the pump manufacturer. So now you have a target flow rate and pressure, the next step is to look for pumps that can meet that flow rate at that given pressure.įlow vs. If you are not using a vacuum line on the fuel pressure regulator (common with in-tank returnless systems), then use the results in the second line. If you run a vacuum line to your fuel pressure regulator, use the first line results (most common). There are two results shown, both show a flow rate in LPH and a pressure. If you are using a turbocharger or supercharger, enter the max boost you plan to run in psi. Base fuel pressure is the static fuel pressure you set at idle, commonly 40-50psi. ![]() Number of injectors is pretty explanatory, just use the number of injectors this fuel system will be feeding (4, 6, 8, etc). If you are unsure, use 90% which will provide a safety margin. This value can be viewed and data logged using most modern engine management systems. Maximum injector duty cycle is the maximum amount of time the injector will be open (100% would be wide open). Once your injector flow rates are nailed down in cc/min, use the calculator below and input all the variables. If you already have injectors, skip this step. Visit the sites below for assistance in selecting fuel injectors for your vehicle. This requires you to have the proper injectors selected for your engine. Essentially, we look at the max flow output of your injectors and make sure we have enough fuel pump energy to support the flow rate. We commonly use a simpler approach to size a fuel pump system, we base it off fuel injector flow. We could talk forever about horsepower and brake specific fuel consumption (BSFC) and how that relates to fuel pump flow, but that tends to require many assumptions and approximations. For some customers, price is a concern and must be seriously considered. Speaking of price, fuel pump prices can vary depending on pump model. But dont completely ignore the options from the other brands, as they may have an offering that fits your application for a very reasonable price. If you feel strongly about a particular brand, then stick to that. Here at Radium, we rarely see fuel pump failures, so we are not biased for or against any particular brand. Many tuners have very strong aligments with certain brands, personal and/or professional. There are 4 main factors to consider brand, price, flow, and fuel type. It uses 6 equally-spaced holes with a 2.18" bolt center.The purpose of this article is to walk through the process of fuel pump selection to understand what is involved when selecting a fuel pump. The 1/16" thick material is a premium quality variation of FKM. This gasket is used for Radium fuel cell fill necks. Machined and Anodized Aluminum Blank Plateġ8-0019 Gasket, 6-Bolt Fill Neck, 2.18" BC This kit blocks off the filler hole on the Radium FCST units. Compatible with Radium Engineering 20-0197-V. The components, materials, and seals are compatible with all fuel types (unleaded and leaded gasoline, diesel, AV gas, methanol, ethanol, E15, E85, etc.). For mating, a 6-bolt flange with a 2.18" PCD bolt circle (as found on the FCST) is required. Includes 20-0549-V Dry Break, 1.5in, Female, Vented as well as an aluminum housing, stainless steel hardware, and a gasket. ![]() Machined and Anodized Aluminum Fill NeckĢ0-0495-V Dry Break, 1.5in, Female, Direct Mount, Ventedĭesigned for direct mounting onto a fuel cell. This kit uses the 20-0148-V Fill Neck Cap (included) so filling is quick and simple. The 20-0197-V Direct Mount Fill Neck and Cap is perfect for filling directly into the fuel cell, as shown. See this blog article for more information on fuel cell filling. Screw threads are the industry standard 1/4"-28. This bolt pattern is used on all Radium Engineering Fuel Cell Surge Tanks. The Radium Engineering fuel cell fill kits can be used on any cell that uses a 6-bolt 2.18" (55mm) bolt circle mounting flange. ![]()
