The BETTER ZL1 fuel pump upgrade alternative: ZL1-FS1000

• Supports up to 700hp
• Applications:
  • Pontiac G8 (all years/models)
  • Holden VE (all years/models)
  • Cadillac CTS-V (2009-2014)
  • Universal applications; aluminium weld-on flange available (see OPTIONS)
  • Custom fuel tanks; requires minimum internal depth of 139mm

SPECIFICATIONS & FEATURES

• Bulkhead Design: We've eliminated the need for 90 degree external fuel hose adapter fittings and simply incorporated a 90 degree thread profile for the Supply & Return ports directly into the bulkhead​

​

• Active Valve System: The ZL1-FS1000 Active Valve System significantly reduces to time required to re-fill the bucket faster than the ZL1 fuel pump module by 83%!​

​

• Venturi Pump: ​The ZL1-FS1000 surge tank features a billet venturi vacuum pump which out performs the ZL1 PLASTIC venturi pump by more than 200%; up to 2 litres a minute of fuel flow!

​

Plug & Play?

While the drop-in surge tank isn't "Plug & Play" per se, the installation can be completed in a mater of hours and will depend on whether the fuel system is setup as a return or non-return system.

Do I Need to Upgrade The Fuel Lines, Fuel Pressure Regulator or Fuel Rail ?

a) Fuel Lines: 

• Non-Return System (Recommended for Supercharged Applications) The factory fuel supply line is sufficient to support the flow & output of compatible fuel pumps (Walbro 255, 460 and 520 fuel pumps); please note, an external fuel pressure regulator MUST be installed and a new fuel pressure regulator return fuel line installed between the regulator and the ZL1-FS1000 surge tank (-6AN recommended)
• Return System (Recommended for Turbocharged Applications): The factory fuel supply is sufficient to support the flow & output of the compatible fuel pumps HOWEVER the fuel rail MUST be upgraded and a return fuel line installed (-6AN return line recommended).

b) Fuel Rail:

• Non-Return System: Testing has revealed that the factory fuel lines and fuel rail is more than sufficient to support the fuel volume without excessive pressurisation.
• Return System: Yes, the factory fuel rail MUST be upgraded.

c) Fuel Pressure Regulator: Yes -The OEM fuel regulator is far too small must be upgraded. See AVAILABLE OPTIONS above- "Fuel Pressure Regulator"

ZL1-FS1000 Surge Tank Additional Features

• Quiet Operation
  • Specially moulded Viton fuel pump noise dampener inserts significantly reduce fuel pump vibration to ensure you have a peaceful in-cabin experience
• Single Fuel Pump Port
  • Perfect fuel pressure control (staged fuel pump operation) & fuel pressure stability due to our design protected 2-to-1 internal fuel pump manifold.
• 100% Ethanol Compatible
  • Zero fuel vapour loss and Zero smell GUARANTEED due to anodising process and materials used
• Quality & Engineering
  • 90% of the components are precision machined from aerospace grade 6061-T6 billet aluminium & the lightweight fuel bucket is designed using best practice engineering principles and stress tested to ensure safety for all motorsport applications. Due to the complexity and the high degree of engineering involved, the lower section of the surge tank is injection moulded with a proprietary super thick, durable and super strong composite fuel (unleaded, race, ethanol) resistance grade of aerospace plastic used by only the most advanced super car manufacturers.
  • Floater valves designs to trap fuel in the fuel bucket
  • Venturi (pump) tube engineered specifically for the GM models.​​
