Product Description

The Aeromotive 18788 Phantom Fuel System Extension Kit is designed for performance-oriented EFI setups that use deep fuel tanks or custom fuel cells. If you're running a Phantom in-tank pump system but your tank depth exceeds the standard hanger length, this kit gives you the extension you need - supporting depths from 10" up to 20". The included 18" hanger ensures your fuel pickup stays submerged, while the foam extension stabilizes the pump and helps prevent cavitation.

With the longer fuel supply line and 20" wiring pigtail, this kit simplifies installation in tanks that sit deeper than typical EFI setups allow. It's ideal for custom tanks, race cars, and classic cars with heavily modified fuel systems. Whether you're building a high-horsepower street machine or a purpose-built race car, the 18788 extension provides flexibility and reliability by allowing your Aeromotive Phantom pump to be properly positioned and powered.
