- Plugs right in to your stock fuel feed line.
- Complete kit includes rail, high quality Aeroquip stainless hoses (3 including full length return line to fuel tank), aluminum AN fittings, regulator, all hardware and instructions. Nothing else needed for install though high volume fuel pump and injectors are usually added.

- Integral spare 1/8 NPT port for addition of fuel pressure sensor or nitrous fuel line (not included.)
