SPE Motorsport S650 Mustang Coyote Fuel Rail Kit

When you’re ramping up power on an S650 Mustang— whether you’re running pump gas, E85, or planning forced induction— the factory fuel rails become the weak link. The SPE Coyote Fuel Rail Kit replaces the stock rails with a high-flow, billet-machined upgrade that supports higher demand and cleans up your engine bay.

Our rails are machined from 6061 aluminum, hard-anodized in black, and use -8AN O-ring style fittings for superior flow and leak-free sealing. We also re-engineered the fuel pressure sensor port angle for better clearance to the wiring harness, and added dual 1/8" NPT ports on each rail — perfect for fuel pressure gauges, sending units, or auxiliary fuel feed (nitrous, pump-gas or E85 systems, etc.). All while retaining the factory fuel pressure sensor.
