Unleash Full Fuel Flow – Say Goodbye to Factory Restrictions

On 2018+ Mustang GTs, the factory fuel rail uses a tiny internal crossover tube that draws fuel from the high-pressure pump inlet and feeds it to the port injection side. This design works for stock power levels but quickly becomes a major restriction under boosted conditions, or high-output builds. The limited orifice starves the port injectors at higher fuel demands, risking lean conditions and inconsistent performance.

The Lawn Racing Fuel Rail Mod Kit eliminates this issue by adding a high-flow external crossover line that bypasses the restrictive OEM passage. This ensures that the port injectors receive the volume they need — consistently and reliably — regardless of power level.

Key Features:

 

  • Bypasses restrictive internal crossover tube
  • Increases fuel volume to port injectors
  • Essential for boosted or E85 setups
  • Plug-and-play install using quality fittings and braided line
  • Compatible with stock and aftermarket fuel systems
    Don’t let your factory rail choke your power. Fix the restriction the right way with the Lawn Racing Fuel Rail Mod Kit.

 

NOTE: PROFESSIONAL INSTALLATION REQUIRED!!

    Fuel Rail Bypass

    This kit absolutely resolved my fuel rail pressure issues for my application. The kit is high quality and well put together, if you are needing to stabilize your fuel pressure at the rail for a non stock application I highly recommend this product!
