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 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 or Thunder Series AVS 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. Edelbrock Dual and Single Feed Line Kits w/ Filter #8133
and #8134 are also available (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.

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.
3.
You must use Edelbrock Adapter #2696 or Adapter & Fuel Line
Kit #2697 when installing a Performer or Thunder Series AVS 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).
You must use an Edelbrock Adapter #2732 when installing a

Performer or Thunder Series AVS Carburetors on Edelbrock manifolds
#2131, #2146, #2151, #2156, #2161, #2171, #2176, #2186, #2191,
#3706, #3761, #3731, and #5486. Without this adapter, a vacuum
leak will occur, affecting the performance of the carburetor. In those
applications, install the adapter as shown (See Fig. 5).
NOTE: Adapter is not needed on #2101, #2104, #2601, #2604 and
#3701.
5.
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 #1727 or #8190.
6.
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.
EDELBROCK CARBURETOR INSPECTION
1.
Check for possible damage to the carburetor.
2.
Make sure all throttle linkages operate freely.
3.
Ensure that all fuel inlet, vacuum ports and throttle bores are free
