Rudy-

As Owen stated, those are Primer cups. The engine has an UPdraft carburetor and a Vacuum pull fuel system. The pump only draws fuel from the tank when the engine is pulling vacuum. fill the priming cups and allow the fuel to run into the cylinders and walla, off she goes.

Some have added an electric fuel pump and bypassed the firewall fuel pump. However, if this decision is made, the fuel pressure must be regulated at no more than 3psi and the venturi needs to be changed in the carburetor.

The venturi is cast into the carburetor I believe and I don't believe you can change that. As the carb float bowl has no way of knowing if the fuel is delivered to it by a diaphragm or rotary pump or gravity from a vacuum tank I don't see why it would be necessary to change (if possible) the venturi.

As Troy mentions, if the fuel is delivered at too high a pressure from a fuel pump (3 1/2 to 5 lbs) it can overcome the needle valve and flood the carb

Thanx Fred, I misspoke, it is the needle valve that gets changed to handle the higher pressures.

Unfortunately those motors usually only seize when they have a cracked block. With periodic use they will run for years with a cracked block, but if left to sit they seize.

As for restoration, I wouldn't spend the money. If the car is pleasant in the visual sense restoring it makes no sense. A better investment would be upgrading your garage with insulation, a dehumidifier, and temperature control to maintain around 45 degrees in winter.
