Aeromotive 18311 Phantom Trifekta Triple 450 LPH In-Tank Fuel Pump Universal

Vehicle Fitment

• Universal Fit - compatible with any custom or factory fuel tank measuring 6 to 11 inches deep; no welding or extensive tank fabrication required

Fitment Notes

• Universal fitment - not vehicle-specific. Customer must verify fuel tank depth (6"-11") and opening diameter compatibility prior to installation.
• Installation requires cutting a single access hole in the top of the fuel tank - no welding or internal tank fabrication required.
• For EFI applications (Return Style): requires Aeromotive fuel pressure regulator P/N 13134 or P/N 13110 (sold separately).
• For carbureted applications (Return Style): requires regulator P/N 13202 or P/N 13212 (sold separately).
• Returnless Style Kit option: requires VaporWorx Fuel Pump Controller P/N 66142 (sold separately) - eliminates fuel pressure regulator and return line. Returnless kit includes an in-tank 85 PSI overpressure failsafe valve.
• Dual ORB-08 outlet ports and one ORB-08 return port require AN fuel lines and high-flow filtration (not included).
• Triple independent electrical bulkheads allow staged pump control - pumps can be activated individually for load management and heat reduction.
• E85 compatible - reduce maximum supported horsepower figures by approximately 30%.
• Not legal for sale or use on emissions-controlled vehicles except on dedicated race vehicles.

Features

• Triple 450 LPH E85-compatible Walbro fuel pumps for massive on-demand fuel flow in a single in-tank assembly
• Patented Phantom Bladder and high-capacity foam baffle system ensures consistent fuel pickup at all tank levels and under hard acceleration, braking, and cornering
• Staged independent pump control via triple electrical bulkheads - run one, two, or all three pumps based on demand
• Custom billet CNC-machined hat with dual ORB-08 main outlet ports and one ORB-08 return port
• Adjustable depth from 6 to 11 inches - fits a wide range of factory and custom fuel tanks
• No welding or tank fabrication required - installs through a single access hole
• 90 PSI maximum continuous operating pressure
• Compatible with gasoline and E85 fuels

Product Description

The Aeromotive 18311 Phantom Trifekta is the ultimate universal in-tank fuel pump solution for ultra-high horsepower street and strip applications. Extending Aeromotive's patented Phantom in-tank technology to its highest output configuration, the Trifekta houses three 450 LPH E85-compatible Walbro pumps in a single assembly capable of supporting up to 3,900 FWHP on carbureted gasoline builds and 3,300 FWHP on EFI - all from inside the factory or custom fuel tank with no welding required.

The system's triple independent electrical bulkheads allow staged pump activation - running only one or two pumps at idle and light load to reduce heat and fuel recycling, then activating all three under full demand. The patented Phantom bladder baffle maintains consistent fuel pickup during hard acceleration, braking, and high-G cornering, eliminating fuel starvation at the tank level. The adjustable 6" to 11" depth range makes the 18311 compatible with a broad range of factory and fabricated fuel tanks, and it is now available in a returnless configuration when paired with the VaporWorx Fuel Pump Controller (P/N 66142, sold separately).
