Vortech Ford 5.0L Maxflow Fuel Rails - Manual

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.
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.

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.
IMPORTANT!: Pressure check the entire fuel sys-
tem 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.
