Designed to work flawlessly with the SMG PWM Twin Pump Fuel System, or any port-injection LT build needing a proper 8AN PTFE feed/return setup.

🟣 FLEX-FUEL CAPABLE — OPTIONAL TURNKEY BUNDLE

Available in two configurations:

1️⃣ Hose Kit Only

Ideal for those who have their own flex system or are completing a return-style conversion around an existing pump setup.

2️⃣ Hose Kit + Flex-Fuel Package

Includes:

• Genuine Continental ethanol content sensor

• SMG plug-and-play harness

• PCM signal extension lead

• Correct placement on the initial feed for optimal cooling and protection
  (Flex sensors do not restrict flow when used in-line on OE-size 3/8 feed circuits.)

If you already own a flex sensor, you may use it as long as no permanent/pressed fittings were installed previously.
