-10% EFI Master Fuel System Kit

This is the exact fuel system kit included with the self-regulated Sniper EFI System Master Kits but with a choice of fuel pumps.  It includes virtually everything most folks will need to convert their carbureted fuel system to an EFI fuel system adequate for the Sniper EFI System.  Also a great choice for self-regulated FiTech EFI kits (disable the FiTech PWM misfeature prior to using this kit.)  This kit is available with either 20 or 40 feet of Earl's Vapor-Guard EFI Fuel Hose.  20 feet is normally fully adequate if you are re-using your existing hard fuel line under the vehicle.  If you need to run both a feed and return then opt for the 40-foot hose.

This kit is recommended for pump or race gas use only. The included fuel pump is not compatible with E-85.

This kit includes:

  • Your Choice Of:
    • TI Automotive (Walbro) GSL396 Inline Fuel Pump (750 HP NA / 620 HP Boosted)*
    • TI Automotive (Walbro) GSL392 Inline Fuel Pump (590 HP NA / 500 HP Boosted)
    • TI Automotive (Walbro) GSL394 Inline Fuel Pump (450 HP NA / 370 HP Boosted)
  • Earl's Vapor-Guard EFI Fuel Line (Choose from 20 or 40 feet.)
  • EFI Fuel Clamps (13)
  • Pre Fuel Filter 20 micron
  • Post Fuel Filter 10 micron
  • -6 AN Female to Hosebarb Adapters (Straight)(4)
  • Return Fuel Bulkhead Port with Nut and Sealing Washers
  • Convoluted In-Tank Fuel Return Hose

If your EFI system is not self-regulated (as is the case with Sniper Stealth and all Sniper 2 and Terminator X systems) you will also need a fuel pressure regulator.  We recommend this great entry-level fuel pressure regulator (applications up to 450 HP).  For more options look here.

*Note: The four-injector Sniper and Terminator X Stealth can only support a maximum of 650 NA / 540 Boosted HP. Having more fuel system capacity than fuel injector capacity is not a bad thing but never attempt to produce more horsepower than the LESSER of your fuel injector or fuel system capabilities.

Note2: The 5/16-inch version is helpful when connecting to an OE fuel tank with 5/16-inch fittings.  However, We do not suggest using 5/16-inch hose with anything larger than the GSL394 Pump.  If you need more pump than that to fuel your engine then you'll want to use 3/8-inch fuel line.

The Mechanical Fuel Pump Block-Off Plate & Gasket is available separately.
