Why a High-Flow In-Tank Pump Matters
Your engine doesn’t care how expensive your turbo is if it’s starving for fuel.
Without upgrading:
- Lean AFR conditions
- Power loss under load
- Inconsistent fuel delivery
- Increased engine risk
Because fuel delivery isn’t optional—it’s survival.
AEM 50-1000 Fuel Pump – Key Features & Functions
High-Flow Fuel Delivery
Improved performance capability:
- Increased fuel volume over stock pumps
- Supports mild to moderate horsepower gains
- Ideal for bolt-on and entry-level performance builds
Because even basic upgrades need more fuel.
Compact In-Tank Design
Efficient fitment:
- Dimensions: 4.055″ x 1.535″ x 1.535″
- Fits in factory fuel tank location
- Maintains OEM-style installation
No need to reinvent your fuel system.
AEM’s High Waft In-Tank Fuel Pump is designed for high performance naturally aspirated and forced induction EFI vehicles. It delivers reliable performance and high volumes of fuel Waft for more or less half the price of comparable performance fuel pumps. The AEM High Waft In-Tank Fuel Pump flows 340 lph at 40 PSI and is in a position to supporting over 1,000 horsepower at 43 PSI.
Stable Fuel Pressure Output
Consistency you can rely on:
- Maintains pressure under acceleration
- Supports proper injector performance
- Helps stabilize AFR
Because pressure fluctuations kill performance.
Durable Construction
Built for daily and performance use:
- High-quality internal components
- Designed for long-term reliability
- Handles increased fuel demand
Because this isn’t a temporary upgrade.
Designed for high output naturally aspirated and forced induction EFI vehicles and tested to Waft 340 lph at 40 PSI
39 millimeter diameter fits most applications; Offset inlet design eases installation and every pump in my view tested. Min Voltage Input – 6 volts. Max Voltage Input – 18 volts
Easy Installation
Straightforward upgrade:
- Drop-in replacement design
- Minimal modification required
- Compatible with many factory fuel systems
Because upgrades shouldn’t require a full teardown.
Why You Need This AEM 50-1000 Fuel Pump
If you’re adding power—even modestly—your fuel system needs to keep up.
The AEM 50-1000 Fuel Pump gives you:
- Improved fuel delivery over stock
- Reliable pressure under load
- Simple in-tank installation
- Support for bolt-on performance upgrades
Because even small builds need consistent fuel.
For gasoline vehicles (pump life could also be diminished when used with E85 fuel); kit includes fuel pump, rubber sleeve and end caps, pre filter, hose, clamps and flying lead
Power rating given at 43 PSI, 13.5 Volt on the pump with a BSFC of .5, Waft capability for horsepower toughen is in the end dependent on fuel hose diameter and system electrical voltage and amperage capabilities
In-Tank design
Fit type: Universal Fit
Ideal Applications
- Daily drivers with bolt-ons
- Naturally aspirated performance builds
- Mild turbo or supercharger setups
- Fuel system refresh upgrades
- Budget-friendly performance builds
Final Verdict
The AEM 50-1000 High Flow In-Tank Fuel Pump is a solid, reliable upgrade for builds that need more fuel without going overkill.
It’s compact, efficient, and gets the job done—no drama.
Because even entry-level performance needs proper fuel delivery.
