    EFI Line Adapters Made Simple

    Russell's ''Push-On'' style fittings are commonly used on GM applications with Electronic Fuel Injection and adapt from AN style hoses to the OEM hard line. All aluminum construction featuring precise thread engagement and a 37° sealing angle for a positive seal at maximum operating pressures. The ''Threaded Cap'' style EFI adapter fittings completely eliminate the plastic retaining clip and replace it with Russell's exclusive screw-in retaining cap for unsurpassed reliability. The dual O-ring seal insures a positive seal under high pressures. They are direct replacements for OEM fuel rail and return line fittings in late-model EFI pressure side application.
