The best fuel cell in-tank pump setup depends on whether you need a complete pump system, a pump hanger, or a replacement pump. The Aeromotive Phantom 340 is best for adding an in-tank system to many tank depths, while the Lanotech hanger suits buyers seeking a single- or dual-pump mounting assembly. The AEM pump is a standalone high-output replacement option. RCI provides a 12-bolt hanger, and EVIL ENERGY offers a fuel cell tank with a level sender and anti-slosh foam.

| Lanotech Twin Hanger | Single or dual pump mounting | Hanger with dual electrical terminals |
| AEM 50-1200 | High-output pump replacement | 340 LPH in-tank pump |
| RCI Fuel Pump Hanger | 12-bolt fuel cell installation | Hanger, fill plate, gaskets, and hardware |
| EVIL ENERGY Fuel Cell | Buyers needing a tank and sender | 15-gallon tank, sender, and anti-slosh foam |
Aeromotive Phantom 340 In-Tank System
The Aeromotive Phantom 340 is a complete in-tank pump system intended for installation inside many fuel tanks measuring 6 to 10 inches deep. Its 340 LPH turbine pump is listed for applications up to 850 horsepower with EFI or 1,000 horsepower with naturally aspirated carburetion.
Best for: Buyers who want a high-flow pump system with an internal baffle and basket assembly. The baffle helps keep the pump submerged and addresses fuel slosh and starvation at low fuel levels.
Consider: Confirm tank depth and application requirements before choosing it. The stated horsepower figures do not, by themselves, verify suitability for every engine or fuel-system configuration.
Lanotech Single Or Twin Pump Hanger
This black-anodized alloy hanger accommodates one or two pumps measuring 39–40 mm. It uses a 12-bolt, 4.75-inch bolt-circle pattern and AN -8 O-ring ports. Dual stainless electrical terminals allow pumps to be staged separately, and the listed seals include Teflon and Viton components for E85-ready use.
Best for: Builders retrofitting an EFI pump into an older carbureted vehicle or planning a single- or dual-pump layout. It was selected for its pump-count flexibility and detailed mounting and port specifications.
Consider: Check the tank’s bolt pattern and pump dimensions. The product information notes that mounting rings, pumps, fittings, and hose may need to be sourced separately.
AEM 50-1200 E85 In-Tank Pump
The AEM 50-1200 is a compact in-tank pump measuring 4.055 by 1.535 by 1.535 inches. It is designed for high-output naturally aspirated and forced-induction EFI vehicles. The manufacturer states that each pump is tested to flow 340 LPH at 40 PSI and lists compatibility with ethanol fuels up to E100, methanol up to M100, and gasoline.
Best for: Buyers seeking a standalone high-output pump with broad listed fuel compatibility. It is a different purchase from a complete hanger or installation system.
Consider: Check the required flow at your system’s operating pressure and verify that the pump fits the selected hanger and tank. The listed flow figure is specifically at 40 PSI.
RCI 12-Bolt Fuel Pump Hanger
The RCI Model 7080A is an aluminum, black-anodized pump hanger kit with a 12-bolt fuel cell fill plate. The listed package includes the pump hanger, gaskets, and hardware. RCI offers different outlet, vent, and return styles to address varying fuel-system layouts.
Best for: Buyers whose fuel cell calls for a 12-bolt plate and who want a hanger with installation hardware included. It was selected as a straightforward mounting option rather than a complete pump system.
Consider: Confirm the exact outlet, vent, and return configuration, as well as pump fitment. The supplied details do not specify a pump model or flow rating.
EVIL ENERGY 15-Gallon Fuel Cell
This aluminum fuel cell measures 19 by 17 by 10.03 inches and includes a built-in 3–90 ohm level sender and internal anti-slosh foam. The listed inlet and outlet fitting size is 10AN. This is a tank, not a standalone in-tank pump, so buyers must separately determine their pump and installation needs.
Best for: Buyers assembling a fuel system who need a 15-gallon tank with a level sender and foam included.
Consider: The product information says it is compatible with fuel and diesel but not alcohol, methanol, water, or ethanol. Do not assume it suits an ethanol-based setup.
Buying Guide: How To Choose A Fuel Cell In-Tank Pump
Do you need a pump, hanger, system, or tank?
A pump moves fuel; a hanger mounts a pump through a tank opening. A complete system, such as the Aeromotive unit, combines a pump with supporting components. A fuel cell is the tank itself. Identify which part is missing before comparing products, since buying a hanger alone does not necessarily provide a pump.
Will the assembly fit your tank?
Compare the bolt count, bolt-circle pattern, tank depth, opening, and pump dimensions with your existing hardware. The Lanotech hanger lists a 12-bolt 4.75-inch pattern and 39–40 mm pump fitment. The Aeromotive system specifies a 6-to-10-inch tank-depth range. Confirm all measurements against your actual tank.
How should you compare pump output and fuel compatibility?
Compare flow at a stated pressure with the needs of your engine and fuel system; do not rely on a flow or horsepower figure alone. Check fuel compatibility too. AEM lists ethanol and methanol compatibility, while EVIL ENERGY specifically excludes ethanol and alcohol. A hanger’s seal material or E85-ready description does not establish compatibility for every other component in the system.
What installation details matter?
Review port sizes, outlet and return layout, electrical terminals, gaskets, and included hardware. Determine whether you need a single pump or staged dual pumps. For a tank purchase, also verify mounting dimensions, sender requirements, and fitting arrangements before planning the installation.
Frequently Asked Questions
Is a fuel pump hanger the same as an in-tank pump?
No. A hanger supports and positions a pump in the tank. A pump is the component that moves fuel, and some products include both while others do not.
Can I use a 340 LPH pump in any fuel cell?
No. Check tank depth, mounting dimensions, pump fitment, fuel compatibility, and the flow required at operating pressure.
What does a dual-pump hanger provide?
A dual-pump hanger can mount two pumps. The Lanotech listing also describes separate electrical terminals for staging the pumps.
Does the EVIL ENERGY fuel cell include a pump?
The listed package includes an aluminum fuel cell, a level sender, and internal anti-slosh foam. It does not list an included fuel pump.
