2018-2025 Mustang Lawn Racing Fuel Rail Mod Kit

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.
