[T3] Fuel pump rod

[Brion Sabbatino]

While on the subject of mechanical fuel pumps. What are others using as replacements? The 1966 model year used an external check valve assembly. Then carburetor models from 1967 on used a fuel pump with a built in check valve. 

I replaced mine (was missing) with a modern version, which I believe has not a check valve.

It worries me. Relying on the needle valves to prevent the flow of gas into the engine; with our heat  and while parked with the nose of the car uphill.

Does anyone know the correct part number I should be looking for? They can be rebuilt? I have been looking for the correct part and part number for some time.
