Fuel Bowl Pump Diaphragm (proper installation)

Before replacing the pump diaphragm cover, check for warpage by laying the cover on a sheet of emery paper which should be on a smooth surface. Remove the sealing bead, if any is present.

Place the diaphragm assembly on the cover, holding the pump lever arm against the diaphragm so that the diaphragm is flat. Don’t forget to install the spring into the bowl first. Install the cover and diaphragm on the fuel bowl and insert the screws finger tight. Release the lever, making certain the diaphragm is loose enough to flex without wrinkling at the edges, also the diaphragm must be able to be raised so that the flange of the steel diaphragm washer touches the inner surface of the cover. These two checks will assure maximum diaphragm travel. Tighten the four screws in two stages, 1/2 torque the first time and full torque on the final stage (5-8 lb. torque).

Tri-Power Carburetors

Rochester Tri-Power carburetor kits. These are
the 2G and 2GC carburetors. The 2GC is the carburetor in the middle and
would have the automatic choke attached. The front and rear carburetor
does not have a choke.Selecting kits for the tri-power carbuetors is straight forward if you
still have the tags attached to the top of the carburetor. Rochester
did not stamp the carburetor number in the side of the carburetor until
1968.Tri-power carburetors use two different carburetor kits. One kit for
the center and the other kit for the front and back carburetors. Each
kit services one carburetor, so to do all three carburetors you will
need three kits.

Be careful because chances are you may not have the original
carburetors. It is rare that we see a tri-power setup that has the
correct carburetors (numbers matching).

Here is an example of a tri-power setup. Notice that the front an rear
carburetors use the same carburetor kit, but the center carburetor uses
a different kit.

What if you don’t have the carburetor tags?

You have to make the best guess and the suggested way is to take the
carburetor apart and carefully compare the old parts with the parts we
have illustrated in the photos, or videos.

Here are the typical carburetor kits used on the Chevrolet carburetors
(prior to 1968)
