4. Disconnect the throttle linkage and cruise control linkage from the throttle lever. Remove the transmission kickdown cable
from the throttle lever (if equipped). Save all linkage clips. They will be used on the new Holley unit.
5. Remove the fuel lines from the TBI. It may be necessary to loosen clamps located away from the TBI in order to remove
the lines from the fittings. Remove the fuel fittings from the TBI. These will be used with the Holley TBI.
6. Remove the TBI and the base gasket from the intake manifold. Place a clean shop towel in the manifold opening to prevent
any foreign material entry into the intake. Clean the gasket surface of any remaining gasket material. Remove the towel
after cleaning the flange surface.
INSTALLATION
1. Install fuel fittings on the Holley TBI. Fuel fittings should be torqued to 22 ft./lbs. Remove the 1/4-20 bolt. Install the stud
(supplied) and 1/4-20 nut (supplied), torquing to 48 in./lbs. Use non-permanent Loctite on the air cleaner studs.
WARNING! Not properly tightening the air cleaner stud can lead to a fire hazard, which in turn can lead to property
damage and/or personal injury.
2. Loosely install the TBI on the intake manifold using the new base gasket provided. Be sure to install the air cleaner base
gasket. Reconnect the fuel lines to the TBI using the new O-rings provided. Torque the TBI bolts first to 6-8 ft./lbs. and
then torque the front TBI bolt to 10-12 ft./lbs. Do not reuse the TBI flange gasket. Always use a new gasket when
reinstalling the TBI unit.
3. Reinstall the electrical connections, except for injectors, and vacuum lines to the TBI. Be sure that the vacuum lines are
connected to the proper tubes and electrical connections are aligned and snapped together tightly.
