FFG Returnless Style Fuel Line System

Returnless fuel line system for Coyote swaps. 25 ft of black braided AN-06 line, quick connects, a billet EFI filter and an Aeromotive pressure gauge in one kit.

  • One line down the frame - returnless halves the plumbing and removes the return-side leak points.
  • The hard fittings are in the box - AN-06 adapters with gauge ports that almost nobody stocks.
  • Clamped properly - insulated clamps sized for Gen 1/2 or Gen 3 routing.

Install Level: Moderate

Requires the PWM fuel management system to control the pump; sold separately.
Fuel pump and tank are not included.
