R35 GTR Fuel Rail Adapter for Flex Fuel

$ 70.00

The Visconti Tuning R35 GTR Fuel Rail Adapter for Flex Fuel is the same black anodized billet aluminum adapter included in our R35 GTR flex fuel kits. It installs on the return side of the fuel rail and connects the OEM fuel rail to our PTFE quick connect flex fuel lines, feeding the ethanol content sensor without cutting or modifying the factory fuel system.

This is our current dual O-ring design. The secondary external O-ring accounts for the variation in inner diameter between factory GTR fuel rails, sealing reliably across the full tolerance range and preventing the seepage that single O-ring adapters could develop over time.

What's included:

  • Black anodized billet aluminum fuel rail adapter
  • Dual O-ring seals
  • Mounting bolts

Use it to replace the adapter from an earlier kit, build out a DIY flex fuel setup on stock rails, or pair it with our R35 GTR Flex Fuel Hardware Kit and a GM ethanol content sensor.
