Vortech Maxflow Fuel System - Manual (Page 2)

B. Fuel Rail/Injector installation
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 system schematic on
page 6.
4. Snap the supplied retainers into the top groove on each fuel
injector as shown at 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 mani-
fold base (the longer rail with the hex plug at the front is to be
installed on the driver's side to provide clearance for distribu-
tor). Secure rails onto the manifold using the four (4) supplied
1/4-20 socket head screws and mounting tabs (previously
attached to fuel rail).
SNAP THE SUPPLIED RETAINER
ON THE TOP GROOVE OF THE
INJECTOR
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.
