FUEL RAIL INSTALLATION

FORD 302/351 WINDSOR

1. Disconnect the fuel injector wiring connectors and remove the existing fuel rails. Remove fuel injectors from manifold base and set aside.

2. Attach the four (4) supplied mounting tabs and eight (8) #10-24 screws to the fuel rail. Orient the tabs so that the slot angle is parallel with the injector bores. The tabs are designed to allow adjustment to compensate for various injector heights and manifold tolerances.

3. Apply a small amount of oil on supplied fittings and O-rings. Install into the rails as shown in the fuel line attachment examples on the following page.

NOTE: Fuel rails are designed to accept -6 straight thread O-ring fittings (9/16-18). Attempting to attach pipe thread (NPT) fittings or any type other than described above will result in damaged threads and possible fuel leakage.

4. Snap the supplied retainers into the top groove on each fuel

injector as shown in Fig. A to the right. Lubricate the injector O-rings with a small amount of oil. Insert the injectors into the fuel rail until the retainer is seated.

5. Install both of the fuel rail/injector assemblies onto the manifold base (the longer rail with the hex plug at the front is to be installed on the driver's side to provide clearance for distributor). Secure rails onto the manifold using the four (4) supplied 1/4-20 socket head screws and mounting tabs (previously attached to fuel rails).

6. Attach fuel supply and return lines. Fuel lines and routing will vary from vehicle to vehicle. See the following page for suggestions.

7. Plumb the fuel pressure regulator onto the return line(s) coming from the fuel rails.

SPECIAL NOTE: Vortech manufactures a billet aluminium fuel block and fittings to adapt a stock configuration 5.0 Mustang fuel regulator to Vortech fuel rails.

Another fuel system accessory is the Vortech Super Fuel Management Unit which is a high-flow stand alone fuel regulator/fuel management unit. Included are all of the necessary pieces to provide various fuel curves and fuel pressure settings for an infinitely adjustable fuel control system.

IMPORTANT!: Pressure check the entire fuel system to confirm that each fitting and injector has a leak-free connection. Make sure fuel lines are routed away from hot exhaust pipes and moving or sharp objects.
