Description<\/h2>\n<\/p>\n

About this item<\/h2>\n

Building an EFI fuel system with mismatched quick connects, insufficient hose length, or missing assembly tools<\/strong> can lead to delays and leaking joints. The 6AN EFI fuel line kit<\/strong> combines 25 feet of reinforced CPE hose with ten AN fittings, four EFI quick connects, separator clamps, a wrench, and gloves. It suits DIY builders and professional technicians fabricating custom supply and return lines in garages, swap projects, street builds, and performance workshops.<\/p>\n

6AN EFI CPE Fuel Line Kit Fitment<\/h2>\n

This universal kit is intended for custom systems using compatible 6AN hose connections<\/strong> and supported 5\/16-inch or 3\/8-inch EFI hard-line interfaces. It is not a direct-fit kit for every vehicle. Measure the factory tube and verify its connection standard before selecting an included quick-disconnect fitting.<\/p>\n

    \n
  • \nAN connection compatibility:<\/strong> Designed for compatible 6AN \/ AN6 hose and 9\/16-18 UNF AN connections.<\/li>\n
  • \nEFI tube compatibility:<\/strong> Includes fittings for supported 5\/16-inch and 3\/8-inch EFI or SAE-style hard-line connections.<\/li>\n
  • \nNPT component compatibility:<\/strong> Includes two 6AN male to 1\/4-inch NPT male adapters for compatible pumps, filters, regulators, tanks, or other components.<\/li>\n
  • \nCompatible fuel types:<\/strong> Compatible with conventional fuel, diesel, race gas, and E15 according to the available product information.<\/li>\n
  • \nCompatible fluids:<\/strong> Also listed for engine oil, coolant, antifreeze, transmission fluid, lubricants, hydraulic fluid, and vacuum applications.<\/li>\n
  • \nCompatible applications:<\/strong> EFI fuel supply, return, cooler, gauge, vacuum, turbo cooler, and oil-feed line fabrication.<\/li>\n
  • \nIncompatible fuel warning:<\/strong> The supplied product image states that the CPE hose is not compatible with E85, E10, or methanol<\/strong>.<\/li>\n
  • \nUniversal-fit notice:<\/strong> Vehicle-specific fuel-pressure requirements, connection locations, tube diameters, and routing are not confirmed by the listing.<\/li>\n
  • \nInstallation requirement:<\/strong> Cutting, fitting assembly, routing, cleaning, and pressure testing are required.<\/li>\n<\/ul>\n

    Key Features of the 6AN EFI CPE Fuel Line Kit<\/h2>\n
      \n
    • \nVerify the EFI Connection Before Ordering:<\/strong> Measure the vehicle’s hard-line outside diameter and identify whether it uses the supported 5\/16-inch, 3\/8-inch, or 3\/8-inch SAE-style connection.<\/li>\n
    • \n25FT Three-Layer CPE Hose:<\/strong> The long continuous hose uses a CPE rubber inner tube, 304 stainless steel reinforcement, and a braided nylon exterior for custom supply and return routing.<\/li>\n
    • \nFour EFI Quick Connects:<\/strong> Multiple hard-line sizes help connect custom 6AN plumbing to supported factory-style EFI tubes without relying on one universal adapter.<\/li>\n
    • \nAN and NPT Fitting Selection:<\/strong> Six straight hose ends, two 45-degree hose ends, and two 6AN-to-1\/4-inch NPT adapters support different component layouts.<\/li>\n
    • \nInstallation Equipment Included:<\/strong> Two separator clamps organize parallel hoses, while the adjustable wrench and gloves support fitting assembly and reinforced-hose preparation.<\/li>\n<\/ul>\n

      \"\"<\/p>\n

      Three-Layer Construction of the 25FT 6AN CPE Fuel Hose<\/h3>\n

      The 6AN hose contains a CPE rubber inner tube, a 304 stainless steel wire reinforcement layer, and a flexible nylon-braided exterior. The reinforcement helps limit hose expansion in pressurized service, while the nylon cover protects the steel layer against abrasion during engine-bay and chassis routing.<\/p>\n

      \"\"<\/p>\n

      Keep the hose away from exhaust heat, moving components, and sharp edges. Support long runs with appropriate clamps and maintain at least the specified bend radius to avoid kinks, localized stress, and internal flow restriction.<\/p>\n

      5\/16-Inch and 3\/8-Inch EFI Quick Connects in the 6AN Kit<\/h3>\n

      The kit provides four EFI quick-disconnect fittings: two 6AN male to 3\/8-inch fittings, one 6AN male to 5\/16-inch fitting, and one extended 6AN male to 3\/8-inch SAE fitting. These components allow a custom 6AN hose system to interface with supported factory-style hard lines.<\/p>\n

      Do not choose a quick connect from vehicle year or model alone. Measure the hard-line outside diameter, inspect the retention profile, and verify the connection standard. A nominally similar tube can use a different bead, clip, or sealing arrangement.<\/p>\n

      6AN Hose Ends and 1\/4-Inch NPT Adapters for EFI Components<\/h3>\n

      Six straight and two 45-degree swivel hose ends provide eight hose termination points. The straight fittings suit direct runs, while the 45-degree fittings help reduce routing stress near pumps, filters, regulators, and tight engine-bay locations.<\/p>\n

      Two additional adapters convert a 6AN male connection to a 1\/4-inch NPT male thread. Apply thread sealant only where appropriate for the NPT connection; do not apply pipe-thread sealant to the AN flare sealing surface.<\/p>\n

      6AN CPE Fuel Hose Compatibility and Fuel Restrictions<\/h3>\n

      The supplied product information lists the hose for conventional fuel, diesel, E15, engine oil, coolant, antifreeze, transmission fluid, lubricants, hydraulic fluid, and vacuum service. The 25FT length is useful when separate supply and return sections must be fabricated from one continuous hose.<\/p>\n

      Do not use the included CPE hose with E85, E10, or methanol.<\/strong> If the vehicle uses another ethanol blend or specialized racing fuel, verify material compatibility before installation or select a suitable PTFE fuel-hose system.<\/p>\n

      6AN EFI Fuel Line Assembly with Wrench and Gloves<\/h3>\n

      The supplied adjustable wrench covers 3AN through 16AN fitting sizes. The protective gloves help shield the installer’s hands from nylon or stainless steel strands that may become exposed when the reinforced hose is cut.<\/p>\n

      Plan both supply and return routes before cutting. Wrap and cut the hose squarely, remove loose strands, fully seat each socket, and inspect all flare and thread surfaces. Flush the completed assemblies and pressure-test every connection before operating the vehicle.<\/p>\n
