INSTALLATION PROCEDURE
BEFORE REMOVING OLD CARBURETOR
1. Determine if the distributor vacuum port is timed (no vacuum
at idle) or full (vacuum present at idle). With the engine at
operating temperature and idling, pull the vacuum advance hose
off of the carburetor and “feel” for vacuum by putting your finger
on the vacuum port (See Fig. 2). If
Fig. 2
your distributor has timed vacuum
advance, you will hook the vacuum
hose from the distributor to the
passenger side vacuum port on
the new carburetor. If it has full
vacuum advance, it will be hooked
up to the driver side port.
2. The stock steel fuel line must be modified to accommodate a
rubber fuel hose as the stock steel line will not connect directly to
the Performer Series Carburetor. The use of the Edelbrock Universal
Fuel Line Kit #8135 is highly recommended. #8135 contains a fuel
filter, rubber fuel hose, and fittings to adapt to 5/16” or 3/8” stock
steel fuel lines (See Fig. 3).NOTE: #1405 and #1406 carburetors
are supplied with a fuel filter. If using #8135 on these carburetors,
the filter included in #8135 can be saved for later use.
WARNING: DO NOT slide the rubber fuel hose directly onto the steel
fuel line, proper fuel fittings must be used to avoid fuel leaks. Be
sure to deburr and clean the stock steel fuel line after modification.

3. WARNING:The use of a new fuel filter (included with #1405 and
#1406) between the fuel pump and carburetor is required. Failure
to do so will void the manufacture’s warranty of the carburetor.
4. You must use Edelbrock Adapter #2696 or Adapter & Fuel
Line Kit #2697 when installing a Performer Series carburetor on a
General Motors Quadrajet or Chrysler Thermoquad intake manifold.
#2697 includes adapter #2696 and fuel line kit #8135. Do not use
an open adapter (See Fig. 4).

5. You must use Edelbrock Adapter #2732 when installing a
Performer Series carburetor on certain Edelbrock intake manifolds.
In those applications, install the adapter as shown (See Fig. 5).

6. Do not use more than 6.5 PSI fuel pressure. Excessive fuel
pressure may cause flooding. If your fuel pressure is too high,
install an adjustable pressure regulator, such as Edelbrock #8190.
9. Remove carburetor, being careful not to spill any dirt into the intake
manifold. Immediately place a clean rag into the intake manifold to
keep foreign objects out.
7. It may be necessary to re-route the fuel line to prevent interference
with the air cleaner. Test fit your air cleaner on your new carburetor
before you begin installation. Look for areas of interference such as
the choke housing, fuel inlet fitting, and fuel line.
PERFORMER SERIES CARBURETOR INSPECTION
1. Check for possible damage to the carburetor.
2. Make sure all throttle linkages operate freely.
3. Ensure that all fuel inlet and vacuum ports are free from packing
material.
CARBURETOR REMOVAL
1. Prior to removal, make sure that the engine is cool.
2. Disconnect the negative battery cable from the battery.
3. Remove air cleaner. Be sure to carefully disconnect any hoses from
the air cleaner and note their location for reinstallation. You may
want to mark them with masking tape for easy reference.
4. Disconnect throttle linkage, kickdown linkage (certain automatic
transmission applications only), cruise control (if equipped) and any
return springs if present.
NOTE: Check carefully for the precise location of all these linkages
and return springs. You may want to mark them with masking tape
for easy reference.
5. Disconnect all wires, tubes, and hoses from carburetor and note
their locations.
NOTE: There should be a maximum of one wire to the electric
choke and one to the idle compensator solenoid (if equipped
with A/C). Any other electrical wiring attached to your carburetor
indicates a computer controlled engine. Edelbrock carburetors will
not function correctly on computer controlled applications.
6. Disconnect the heater tube from the choke housing (if so equipped).
Edelbrock carburetors do not use the hot-air-style choke, so this
tube may be left disconnected with no problems. If you would like to
cover this opening on a stock manifold, you may be able to use the
appropriate Edelbrock Choke Adapter Plate: #8901 for small-block
Chevrolets; #8961 for big-block Chevrolets; #8951 for Oldsmobile
V8s; #8971 for 351-M/400 Fords; #8981 for 351-W Fords.
10. Remove old mounting gasket and thoroughly clean mounting
surface. Compare old carb gasket to the gasket included with your
Edelbrock carburetor. If there is a difference in bolt pattern or bore
spacing, an adapter will be required (see “Before Removing Old
Carburetor”, steps #4 & #5).
CARBURETOR PREPARATION
1. Compare the throttle arm
of your new carburetor
with the old one to be
Ford Throttle Lever #1483
bolts to carb throttle arm
sure that all required
linkages will hook up.
Install the proper throttle
and transmission linkage
for your particular
application. Throttle stud
is removable and must
be installed in the proper
Fig. 6
location. Chrysler vehicles with automatic transmission will require
Throttle Lever Kit #1481. Ford vehicles with automatic transmission
and cable linkage will require Throttle Lever Kit #1483 (See Fig. 6)
and Throttle Cable Plate Kit #1490 (for 289-302), #1491 (for 351W), #1493 (for 351-C & 351-M/400), or #1495 (for 429/460).
2. Check and prepare carburetor for proper vacuum fitting installation
(EGR, power brakes, PCV, distributor, transmission, etc.), using the
supplied vacuum caps, “T” and hose when applicable. If vacuum
port at rear of carb is not used, plug with the 1/4 NPT pipe plug
supplied (Except marine models, port is not drilled).
3. On electric choke models (See Fig. 7), remove one choke housing
retaining screw and install eyelet end of choke ground wire (black)
to the choke housing, and reinstall the screw. Connect clip end of
choke ground wire to negative (–) spade terminal on choke housing.

7. Carefully remove the fuel line from the carburetor. TAKE EXTREME CARE NOT TO SPILL ANY EXCESS FUEL. Place a rag underneath
the fuel line to absorb any spillage that may occur. Certain models
require two wrenches to remove the fuel line; one to hold the fitting
on the carburetor and the second to turn the fitting on the fuel line.
Use a tubing wrench to avoid rounding the tube fitting nut.
8. Remove mounting nuts or bolts and washers. Be sure to put them
where they won’t fall into the intake manifold upon carburetor
removal.
