Description 

Instructions for current Coyote fuel rail kits (PDF)
Instructions for discontinued Coyote fuel rails (PDF) <-Can be identified with a laser engraved radioactive symbol.

This kit is compatible with all vehicles that use the 5.0L Ford Coyote modular engine including the direct injected 2018+ Mustang GT, 2011-2017 Mustang GT, Ford Shelby GT350, Ford Falcon, Ford F-150, etc. It can be used with OEM returnless or aftermarket return fuel systems. It also fits the Ford Racing Boss 302 Manifold.

The rails feature a large 0.69" internal diameter bore to suit even the most fuel hungry engines. They are CNC machined from solid 6061 aluminum, black anodized, and laser etched for a high quality surface finish. Each rail has three 8AN ORB (3/4-16 female) threads and one 1/8" NPT female port. Adapter fittings can be found HERE and HERE. Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. Additionally, these rails have provisions for the factory injector retaining clips, as shown below.

This kit is compatible with all fuel types including popular alcohol mixtures such as E85.

NOTE: The parts below may be required for the specific vehicle if the 20-0434 Fuel Rail Plumbing Kit (described below) is NOT purchased.
For the 2018+ Mustang GT, Radium P/N: 14-0358 (shown below) is required to adapt the OEM direct injection pump feed hose.

For the 2018+ Mustang GT and the Shelby GT350, Radium P/N: 14-0359 (shown below) is required to adapt the OEM fuel sensor.

INCLUDED:

20-0433 Ford Coyote Fuel Rail Kit: 
-Black Anodized Laser Etched Aluminum Fuel Rails (x2)

OPTIONAL:

The 20-0434 Fuel Rail Plumbing Kit, Ford Coyote allows for an OEM bolt-on affair. It is compatible with ALL Coyote engines including the S197 Mustang GT, S550 Mustang GT, Shelby GT350, and the 2018+ Mustang GT (with direct injection). This kit eliminates any unnecessary fuel hoses that route over the top of the engine preheating the fuel. It plumbs the fuel rails starting from the SAE quick disconnect fitting upstream near the firewall. The rails are ran in parallel for even fuel distribution with the use of our high flowing billet aluminum Y-adapter fitting. All hoses are high quality PTFE compatible will all fuel types including E85. Billet aluminum O-ring plugs are included for all unused ports. Radium P/N: 14-0358 and Radium P/N: 14-0359 are included for the 2018+ Mustang GT and the Shelby GT350.

NOTE: If a fuel pressure gauge is required, go HERE to get the appropriate adapter. 

Fuel Pulse Damper(s)
Do I need pulse dampers? The opening and closing of the injectors creates pressure pulses in the fuel rail, which can lead to unstable fuel pressure. This issue is further enhanced with the noise created by the direct injection system on 2018+ Coyote engines. In order to achieve a safe and consistent rail pressure, pulse damper(s) should be used (especially with high flow injectors). The internal diaphragm will absorb oscillation pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle. Radium -8AN ORB Fuel Pulse Dampers can be used on any fuel rail port provided there is applicable space.
