Product Description

The Aeromotive 18688 Phantom 340 Stealth Fuel System is a universal in-tank upgrade engineered to provide high-flow, reliable fuel delivery inside virtually any fuel tank. Designed to fit tank depths from approximately 6" to 11", this modular assembly features a 340 Stealth electric fuel pump mounted within a baffled basket that controls fuel slosh and keeps the pump submerged during hard acceleration, cornering, or braking. Its black anodized hanger assembly integrates (3) ORB-06 ports for return, supply, and vent - enabling modern fuel system plumbing for both EFI and carbureted engines when used with a return-style regulator setup. 

This Phantom system's universal design allows the height of the assembly to be cut to match your tank's specific depth, making it adaptable to many plastic, steel, or aluminum tanks without the need for external fuel cells or extensive fabrication. The included high-flow pre-pump filter offers debris protection, while the internal baffle helps reduce vapor lock and fuel starvation issues common in performance environments. Whether you're building a high-horsepower EFI street car or a carbureted race machine, this system gives you quiet, efficient, and dependable fuel delivery.

Rated with high-flow capability, the Phantom 340 system can support significant performance levels - up to roughly **700 HP EFI with forced induction**, **850 HP EFI naturally aspirated**, **850 HP carbureted with forced induction**, and **1000 HP carbureted naturally aspirated** depending on setup, regulator choice, and fuel type. Always pair this system with an appropriate return-style fuel pressure regulator and properly sized plumbing to ensure optimal performance and safety. Note: this part **is not legal for sale or use on emission-controlled vehicles** except where allowed as direct OEM replacement matching specifications.
