JBtuned K-Swap Fuel Line Kit - Integra Civic - OEM Filter to Rail and Returns

We have created a fuel system design specifically for your Civic or Integra running a K-Series engine. This kit is designed to use your OEM Filter and factory feed and return lines.

This Kit is everything you need to supply your kswapped car with fuel and add a return line to the engine for better tune-ability.

This kit requires that you have an aftermarket regulator mounted to the driver side shock tower. (This is one of the most common mounting points).


  • Hose - We use high quality nylon sheeting reinforced by a layer of stainless steel. Strength and flexibility.
  • Fittings- Anodized polished black reusable hose ends made from 6061 aluminum.
  • Design - No cavitation is the goal - JBtuned uses full flow fittings on all of our kits to prevent cavitation of fuel and to provide consistent pressure with minimal restrictions. Compare this to other kits on the market with sharp 90 degree bends coming off the filter or rail.
