Aeromotive 18311 is the Trifekta Phantom in-tank fuel-pump kit with three 450 LPH pumps and the Phantom bladder/baffle system.
In-tank mounting: this is not an externally mounted pump. The kit uses a 6-inch top cap and requires a 4.5-inch tank opening. It is a universal conversion that requires checking tank depth, clearance and fuel-system design.
The kit provides the in-tank pump mounting system. Wiring, fuel lines, filtration, pressure regulation and the fuel-level sender require separate planning. Follow the exact 18311 instructions for ports and plumbing; do not substitute specifications from a returnless/controller package.
Aeromotive restricts use on emissions-controlled vehicles except where it qualifies as a direct replacement matching OEM specifications.
