Spool Stage 3 Bucketless LPFP | BMW N54

The Spool Stage 3 Bucketless LPFP is an extreme performance low-pressure fuel pump upgrade for BMW N54 engines. This system is designed for high-power projects that demand maximum fuel flow, especially when running on E85 and combined with port injection solutions.

The bucketless design ensures consistent fuel delivery even during hard acceleration and on the track, where traditional solutions can suffer from fuel sloshing in the tank.

Key Features

• Top-tier flow capacity: Designed for very high-power N54 builds
• 100% E85 compatible
• Bucketless design: Improves fuel delivery during aggressive driving
• Modular and performance-oriented design
• Plug & Play installation (depending on the model)
• Compatible with port injection systems

• Temperature resistance: up to 450°F (~232°C)
• Connections: 6AN + CNC-machined aluminum fittings
• E85 compatibility: Full compatibility with ethanol fuels
• Significantly more durable than traditional rubber-based fuel lines
