VTT “Double Barrel” HPFP kit. Our Double barrel kit adds a second HPFP to your existing HPFP system. Using the same mounting system as our “Single Barrel” Kit, you now leave your stock HPFP in place and mount an additional pump on the accessory drive, then using our custom high / low pressure feed lines, modified fuel rail, and activation system, the second pump is now run on demand, and that demand can be user adjusted for activation point, and fuel added.  This kit requires an external controller, any Port injection controller on the market can be used, such as Split Second AI6, as well as Syvecs, haltech, AEM,  etc. You can purchase an EV-6 to HPFP plug in play cable to easily plug your HPFP into your existing controller. If you do not have one, you can add it from the drop downs.

Please choose if you are using the stock intake manifold or Front Facing aftermarket. Front Facing Aftermarket requires a custom HPFP hose for the secondary pump and is an extra $50.

Included in the “Double Barrel” kit:

  • VTT Billet HPFP drive housing
  • VTT Billet Stainless Steel drive shaft (pre-assembled in housing)
  • High-speed German ball bearings rated at 17,000RPM (pre-assembled in housing)
  • VTT Billet HPFP pulley

  • VTT “Double Barrel” modified fuel rail (core charge applies)
  • New Serpentine belt
  • Plug and play wiring harness for the pump on the belt
  • Secondary HPFP controller (optional, if you do not already own a capable Controller)
  • Plug, and play adapter harness if you already have a controller
  • All hardware required for assembly


A $200 fuel rail core charge is added and will be refunded once Fuel rail is returned according to our core return policy.

Add one or two brand new HPFP’s to make sure your VTT Double Barrel Shotgun HPFP upgrade is working to its full potential!

The Shotgun system fits most N54 models, and N55 models 2011 only. If you have a question about your model please drop us an email!

Note: This product does not fit E6X 5 series chassis, XI models or models with Active Steering! The Shotgun HPFP system works by spinning your stock HPFP faster, thus increasing its fuel flow significantly. This requires upgraded LPFP’s on the supply side if you cannot supply enough fuel for the increased flow your rail pressure will not improve. We suggest running a minimum of two Walbro 450’s on the supply side for proper operation of the shotgun system.
