Install AEM Fuel Pump: Position the new pump, secure it, and reconnect fuel lines and wiring
Positioning the new AEM fuel pump is a critical step that demands precision. Unlike universal pumps, AEM models often feature a modular design optimized for specific fuel delivery rates (e.g., 255 LPH for high-performance setups). Begin by aligning the pump’s inlet and outlet ports with your vehicle’s existing fuel lines, ensuring a straight, unobstructed path to minimize flow restriction. Use a template or the old pump’s mounting holes as a guide, but verify compatibility with AEM’s installation manual, as some models require a custom bracket for secure mounting. Pro tip: If your vehicle lacks a dedicated fuel pump mounting surface, consider a universal hanger kit, but ensure it’s rated for the pump’s weight (typically 3-5 lbs).
Securing the pump is where many installations falter. AEM pumps often include a rubber isolator to dampen vibration, which must be positioned between the pump and mounting surface to prevent premature wear. Torque the mounting bolts to 12-15 ft-lbs, using a torque wrench to avoid over-tightening, which can crack the pump housing. For in-tank installations, double-check that the pump’s strainer is submerged at all fuel levels—a common oversight that leads to aeration and fuel starvation under hard acceleration. If your tank’s depth exceeds 8 inches, consider adding an extended pickup tube, available as an AEM accessory.
Reconnecting fuel lines and wiring is a step that separates a functional install from a reliable one. Use AEM’s provided hose clamps (rated for ethanol-blended fuels) to secure the lines, ensuring a minimum 1-inch clearance from hot surfaces like exhaust manifolds. When splicing wiring, opt for a relay-controlled circuit to prevent voltage drop, especially in pumps drawing over 15 amps. AEM’s pumps are polarity-sensitive, so verify the positive and negative terminals match your vehicle’s wiring diagram. For added safety, install an inline fuse (20-amp for most models) within 12 inches of the battery connection.
A comparative analysis reveals that AEM’s plug-and-play harness, included with some kits, simplifies this step but may require adapter plugs for older vehicles. If using a universal wiring setup, test the pump’s operation before finalizing connections—a brief 10-second activation ensures proper flow direction and eliminates air pockets. Lastly, pressure-test the fuel lines at 60-80 PSI (AEM’s recommended range) to detect leaks, particularly at quick-disconnect fittings, which are prone to failure if not fully seated. This meticulous approach ensures not just functionality, but longevity in high-stress applications like racing or turbocharged setups.

Test and Verify Installation: Reattach battery, check for leaks, and ensure proper fuel pump operation
Once the AEM fuel pump is installed, the final and most critical phase begins: testing and verification. Start by reattaching the battery, ensuring all connections are secure and corrosion-free. This step is non-negotiable, as it powers the system and allows for immediate feedback on the installation’s success. A loose or improperly connected battery can lead to erratic pump behavior or even system failure, so double-check polarity and tightness before proceeding.
With the battery reconnected, the next priority is to check for leaks. Fuel leaks are not only hazardous but also indicate improper installation. Begin by inspecting all fuel lines, fittings, and the pump itself for any signs of seepage. Use a spray bottle with soapy water to detect even the smallest leaks, as fuel may not be visible to the naked eye. Allow the system to pressurize for a few minutes, then reinspect. If leaks are found, address them immediately by tightening connections or replacing faulty components. Ignoring this step could lead to fire risks or fuel starvation.
Once leak-free, the focus shifts to ensuring proper fuel pump operation. Start the engine and listen for the pump’s priming cycle, a distinct humming sound that confirms it’s functioning. Monitor fuel pressure using a gauge to ensure it matches the AEM pump’s specifications, typically between 40–80 PSI depending on the model. If pressure is inconsistent or absent, check for clogged filters, faulty wiring, or incorrect pump orientation. A properly operating pump should maintain steady pressure under load, so simulate driving conditions by revving the engine or taking a short test drive to verify performance.
Practical tips can streamline this process. For instance, use a fuel pressure tester with a quick-disconnect fitting to simplify pressure checks. If the pump fails to prime, verify the inertia switch (if equipped) hasn’t tripped, a common oversight. Additionally, consult the AEM manual for model-specific diagnostics, such as error codes or LED indicators. By methodically testing and verifying the installation, you not only ensure safety but also maximize the pump’s efficiency and longevity, transforming a complex upgrade into a reliable performance enhancement.
