Description

The Holley EFI Fuel System Kit (P/N 526-7) is engineered to be the perfect addition to your Sniper EFI or Holley EFI system, providing a tailored fuel system for your EFI setup. This kit integrates Holley fuel pumps, regulators, and filters with quality Earl's plumbing components. The Vapor Guard fuel hose is constructed with multiple layers for superior fuel isolation and durability. Its innermost barrier layer resists heat and aggressive fuels, while the middle Vapor Guard Barrier, a thermoplastic layer, virtually eliminates fuel vapor escape. The exterior cover provides extreme tolerance to heat and ozone, offering a robust defense against hose deterioration. Key features of this kit include 40 feet of 3/8-inch Vapor Guard Fuel Hose, a 12-920 Fuel Pump, and both pre and post-fuel filters. It also contains the necessary hardware and a bulkhead fitting for returning fuel into the tank. This multi-layer rubber hose is designed to withstand the corrosive properties of modern fuels and is multi-fuel compatible, approved for use with leaded and unleaded gasoline, diesel, biodiesel, E-85, 100% methanol, ethanol, and gasohol fuels. The Sniper EFI system requires a return fuel line to the fuel tank, and this kit includes the necessary components for such an installation.
