PAGE 13 This shield attaches to the outermost exhaust manifold bolts and protects the corrugated hose from being damaged by the heat from the exhaust manifold. I understand Dan Evans is having this shield reproduced and I heard that Jim Weatherly is as well, so check with both of them if you need one.: The F code Thunderbird uses the same Exhaust heat riser valve and the other Thunderbirds but it is installed with the counter weight on the engine side rather than the inner fender side so it is not obstructed by the air cleaner.  The first picture here is of my heat riser properly installed and the second picture is of someone elses car where it is improperly installed. A unique dual point distributor is also used on the F birds. here you can see the two point mechanisms as well as the condensor mounted on the lower outside of the distributor rather than inside as typical. This vacuumn advance diaphram is also unique to the F birds: (I have a couple extras if you need one)

The fuel pump for F birds has an additional threaded opening in the side in which a pressure line comes in from the blower. It enters the fuel pump below the diaphram and adds pressure to help the spring in the pump keep up with the additional demand for fuel when accellerating. The fuel filter is turned upside down and it has an additional line coming out the bottom which is a fuel return line to the tank in which unused fuel is discharged. Here you see the two fuel lines. One for supply and one for return. And here is how they connect at the tank. The supply line connects as all Tbird fuel lines to the tank but the return line connects into the fuel filler breather line as pictured: The carburetor is another unique item and is fitted with a couple additional openings for vacuumn and fuel delivery and should be stamped "EDBD 9010-AA (or -AB") Mine is -AA: Next is the unique carburetor Bonnet. This one is an exact reproduction of the original by Frank Rice. It helps to keep the carburetor from blowing apart with the increased pressure from the blower: At the back of the intake manifold below the carburetor mounting platform is a special pressure relief valve. Originals are usually long gone but fortunately Jim Weatherly makes an excellent reproduction valve: Return to TOM MARUSKA CARS Move ahead To PAGE 14
