Edelbrock 1813 - Manual (Page 3)

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,
or #1727.
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.
THUNDER SERIES CARBURETOR INSPECTION
1.
Check for possible damage to carburetor.
2. Make sure all throttle linkages operate freely
3. Ensure that all fuel inlet and vacuum ports are free from packing
material.
5. You must use an Edelbrock Adapter #2732 when installing a
Thunder Series Carb on some Edelbrock manifolds
(See Fig. 5).
Refer to the instructions included with the manifold for details.
3. Always use a new fuel filter. Failure to do so will void the
warranty.
4. Edelbrock Adapter #2696 or Adapter/Fuel Line Kit #2697 must be
used when installing a Thunder Series Carburetor on a General
Motors Quadrajet or Chrysler Thermoquad manifold.
#2697
includes Adapter #2696 and Fuel Line Kit #8135 (See Fig. 4).

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 fully warmed up and idling, pull the vacuum hose off of the
carb and "feel" for vacuum by putting your finger on the vacuum
port
(See Fig. 2). If your distributor has timed vacuum advance,
hook the vacuum hose from the distributor to the passenger side
vacuum port on the carburetor. If it has full vacuum advance, hook
it up to the driver's side vacuum port.
2. The stock steel fuel line must be converted to either a fuel
resistant rubber hose or one of the Edelbrock fuel line kits. The
stock steel fuel line will not connect to the Thunder Series
Carburetors. Use one of the Edelbrock Fuel Line and Filter Kits
#8133 (dual feed), #8134 and #8135 as seen on the Edelbrock
website or in the Edelbrock catalog
(See Fig. 3).
NOTE: After cutting fuel line, remove sharp edges and clean
out any chips.
