AEM Performance 340 LPH E85 high-flow in-tank fuel pump

AEM 340LPH E85 high-flow in-tank fuel pumps feature a robust internal design built to withstand the low lubricity of ethanol and methanol fuels. They are tested for use with ethanol fuels up to E100, methanol up to M100 and all gasolines. The pump is designed for in-tank installation in high-performance naturally aspirated and forced-induction cars. Its compact 39 mm diameter suits most applications, and the offset inlet makes installation easier. Every pump is tested to flow 340 LPH at 40 PSI before it is packed.

AEM 400LPH Inline Fuel Pump with Metric Fittings

The AEM 50-1009 is a high-flow external (inline) fuel pump for modified and high-performance engines where fuel starvation must be avoided. “Metric” refers to the fittings – M18x1.5 inlet and M12x1.5 outlet. The body follows the industry-standard “044” envelope, so the pump fits 044-style brackets.

Specifications

• Manufacturer part number: 50-1009
• Type: external (inline)
• Flow: 400 LPH at 40 PSI, 340 LPH at 73 PSI, 270 LPH at 120 PSI
• Inlet: M18x1.5 (female)
• Outlet: M12x1.5 (male)
• Body diameter: 60 mm
• Weight: 1015 g

Fuel compatibility

• All types of petrol
• Ethanol blends E85/E90
• Pump life is reduced with 100% alcohol fuels

What's in the box

• Fuel pump
• Check valve fitting
• Terminals, nuts and terminal boots
• Instructions

Important: The mounting bracket is not included. If you're unsure about compatibility, send us your VIN.

AEM 340LPH In-Tank Fuel Pump

When you tune or upgrade an engine, the stock fuel pump is sometimes not strong enough to deliver the fuel it needs. The consequences can be serious – in the worst case, engine damage from knock (lean mixture, overheating).

The AEM 50-1000 fuel pump flows 340 LPH and is a reliable way to supply enough fuel for more powerful builds. It is designed for petrol vehicles.

Specifications

• Manufacturer part number: 50-1000
• Flow: 340 LPH at 40 PSI
• Mounting: in-tank, offset inlet
• Pump diameter: 39 mm
• Inlet: 11 mm
• Outlet: 8 mm
• Weight: 354 g
• Fuel: petrol (not intended for E85)

What's in the box

• Pump
• Washable fuel filter
• Wiring and connectors
• Hose, clamp and accessories

Important: Before ordering, check that the pump size suits your fuel tank. If in doubt, send us your VIN.

AEM 320LPH E85 In-Tank Fuel Pump
