RCI Fuel Pump Hanger, 12 Bolt Round, 8 AN Fittings
Best for retrofitting a fuel cell with customizable outlet, vent, and return configurations. The kit includes a 12-bolt fuel cell fill plate and a pump hanger, making it suitable for buyers upgrading older tanks or building a flexible EFI system. This option is ideal for performance builds needing multiple port choices and a sturdy aluminum structure.
Who it’s best for: builders who want modular fuel-cell plumbing and ready-to-fit hardware. Why selected: it supports varied configurations and reduces the need for custom fabrication. Caution: verify compatibility with your specific 12-bolt flange pattern and AN fittings before ordering.
Holley 12-147 Fuel Cell EFI Pump Module
Best for upgrading a fuel cell to EFI without major modification. This module drops into a standard 12-bolt flange with a billet top flange housing, featuring an 8AN inlet and 10AN outlet port plus a fuel filler cap. It’s a straightforward EFI upgrade for existing fuel cells, reducing retrofitting effort.
Who it’s best for: performance enthusiasts seeking a plug-and-play EFI upgrade. Why selected: streamlined EFI integration with clear port options. Caution: ensure your tank’s wiring and mounting space align with the billet flange dimensions.
EVIL ENERGY EFI 255LPH In-Tank Fuel Pump
Choose this for high-flow EFI needs in a pump housed inside the tank. With a stated test flow of 255LPH at 43 PSI, it’s designed for steady fuel delivery and reduced lean conditions during acceleration. It’s intended for 12V DC EFI systems and gasoline use.
Who it’s best for: builders prioritizing high-flow EFI delivery. Why selected: strong flow suitable for performance engines. Caution: high-impurity fuel may shorten pump life and reduce efficiency; verify fuel quality and regulator settings.
Lanotech Twin 39-40mm Fuel Pump Hanger Assembly
Best for dual-pump setups in 39-40mm configurations. This anodized black alloy hanger supports one or two pumps, with dual stainless terminals for staged operation. It is E85 ready and uses teflon seals and viton o-rings, with AN-8 O-Ring Ports.
Who it’s best for: enthusiasts retrofitting EFI pumps into older tanks or running dual-pump EFI systems. Why selected: durable hanger capable of staging two pumps independently. Caution: designed for specific 39-40mm pumps; confirm compatibility with your chosen pumps and tank depth.
Lanotech Fuel Cell Single/Twin Pump Hanger (Adjustable Height)
Best for tanks with variable depth. This hangar handles 39-40mm pumps and features adjustable pump height to fit tanks from 180mm to 280mm. It’s anodized black with stainless terminals and TEFLON seals for E85 readiness.
Who it’s best for: builders needing adaptable mounting height in different tanks. Why selected: gives flexibility for different tank geometries. Caution: height adjustment adds mounting complexity; verify clearance with filler neck and sender assemblies.
EVIL ENERGY External Inline Fuel Pump 300 LPH
Best for 12V EFI systems needing high flow in an inline format. The pump provides multiple flow points (200–300 LPH) at different pressures, with compatibility for gasoline and race fuels. It’s suitable as an upgrade when an inline solution is preferred over an in-tank option.
Who it’s best for: builders seeking an external high-flow pump. Why selected: strong flow options and versatile fuel compatibility. Caution: inline pumps may require additional fuel line routing and heat management in tight engine bays.
Buying Guide
What pump type should you choose for a fuel cell?
- In-tank vs. external: In-tank pumps simplify installation and reduce heat exposure, while external or hanger-based solutions offer easier access for maintenance and more flexible plumbing.
- Single vs. dual pumps: Dual-pump setups improve reliability and allow staging for different driving regimes; consider a hanger with dual terminals for independent control.
- Flow and pressure: EFI systems typically require higher flow at moderate pressure; confirm your regulator’s target pressure and the pump’s maximum flow.
- Fuel compatibility: Ensure the pump materials and seals are compatible with gasoline, race fuels, or ethanol blends present in your tank.
- Tank compatibility: Check bolt patterns, flange sizes, and available height to avoid clearance issues with senders, caps, and filler necks.
Practical considerations
- Ease of retrofit: If retrofitting an older tank, a hanger system with an adjustable height or a plug-in EFI module can reduce fabrication.
- Thermal management: High-flow pumps generate heat; ensure adequate ventilation or cooling in enclosed trunks or wheel wells where applicable.
- Fuel quality: Impurities can affect pump life; use clean fuel and consider a compatible filter kit in the installation.
- Wiring and installation: Confirm wiring harness length and compatibility with your vehicle’s electrical system; professional installation is advised for complex EFI setups.
FAQ
- What is the difference between an EFI pump module and an in-tank pump?
An EFI pump module is designed to drop into a fuel cell and provide an integrated solution with defined inlet/outlet ports, while an in-tank pump is a standalone unit installed inside the tank. - Do I need a dual-pump setup for a fuel cell?
Dual pumps can improve reliability and support higher horsepower levels by providing staged fueling, but not all builds require two pumps. - Can I use an external inline pump for a fuel cell?
Yes, inline pumps are common for certain setups, but they may require additional mounting, plumbing, and heat management considerations. - Will these pumps work with ethanol blends (E85)?
Many hangers and pumps are designed for E85-ready use, but always verify material compatibility and seals with your specific fuel blend. - How do I decide the best height for a fuel cell hanger?
Choose a height that allows adequate pump submersion and clearance for the tank’s internal components, reducing air ingestion and cavitation.
