Precision Raceworks G-Series BMW & Supra A9x Billet Fuel Pump Top Hat

OVERVIEW

The "top hat" caps the fuel pump module inside the tank — where fuel line and wiring connections meet the pump, and where clearances get tight once you add an external pump for a hybrid build. Precision Raceworks' billet top hat is machined to properly accommodate their upgraded/hybrid pump setups, replacing the factory plastic top hat with a stronger, purpose-built billet aluminum piece and eliminating the melted-connector failure mode of the factory part.

SPECS

• CNC-machined, anodized billet aluminum construction — replaces the factory plastic top hat and its known-weak electrical connectors
• 2 electrical bulkheads with connectors (6 wires each)
• 2 electrical connectors pre-wired to run the factory pump and floats
• 3/8" male quick-connect output compatible with the factory line
• 7.89mm male quick connect for the tank, plus a PTFE in-tank line with 7.89mm quick connect for the factory filter
• Two accessory port block-off plates and a sensor mounting bracket (not needed on all cars)
• Built for hybrid pump setups — clearance and mounting for AFS, surge tanks, Stage 3, Stage 4, and more
