Description
The AEM 50-1220 is an in-tank fuel pump for performance fuel systems requiring additional delivery capacity. Its published rating is 340 liters per hour at 40 psi; operating pressure is therefore an essential part of pump selection.
Design and operation
The pump is designed for gasoline and alcohol fuels, including ethanol through E100 and methanol through M100. That compatibility applies to the pump itself: hoses, seals, injectors and other wetted components must also be suitable for the chosen fuel.
Key specifications
- Manufacturer part number: 50-1220
- Rated flow: 340 LPH at 40 psi.
- In-tank configuration.
- Ethanol and methanol fuel compatibility.
- Select by the full 50-1220 part number and physical connection arrangement.
Installation and compatibility
Compare pump dimensions, inlet and outlet arrangement, electrical connections and mounting requirements with the existing fuel module. Do not assume a complete vehicle-specific hanger or installation solution is included. Evaluate wiring and supply voltage alongside fuel demand at the intended operating pressure.
Maintenance
Check fuel-system pressure and inspect for leakage after installation. Use filtration and service practices appropriate to the fuel and installation.
Important application notes
A larger pump alone does not establish a safe horsepower limit or complete an ethanol conversion. Injector capacity, regulation, wiring and engine calibration must be evaluated together.
