Return Line

Starting in 1975, North American B210s were fitted with a fuel return line. Here's what the Nissan publication "Introduction of Datsun B210 (1975 model)" says:

Fuel return system
For preventing abnormal fuel temperature rise, the fuel return system has been installed. In this system, fuel from the fuel tank is delivered to both the carburetor and fuel tank.
The fuel return line services to return a part of the fuel to the fuel tank to suit different engine operating requirements, preventing the possibility of fuel heated flowing through the fuel line inside the engine compartment, and elminating "percolation" inside the carburetor.

Venting

Datsun 1200 in most parts of the world vents the fuel tank to the atmosphere. A simple hose loop goes from the filler tube up above the tank and back down towards the ground. The loop is to prevent a siphoning effect.

EVAPO

In Australia after 1978, and Japan after 1974, and all years in North America 1200s used the Evaporative emissions control system.

With EVAPO, the tank is not vented directly to the air. Instead, fumes are captured by the Evaporate Emission control (EVAPO) system. For details, see Fume Control.

Sedan

Note that the USA B110 sedan tank uses a 2-piece filler hose (there's a small hose inside the bigger one). This is for the EVAPO (emissions market) vehicles:

This hose is NLA (No Longer Available) in US, Canada or Japan. However, the regular single hose can be fitted as follows:

US EVAPO

Expansion Tank is a liquid/vapor separator. This was replaced by a check valve in the B210 sedan, while B210 coupe continued to use the separator tank. In the B310 this tank was removed and all models used the check valve.

Parts Sources

Nissan. In North America, call Ericksen Nissan's toll-free number. If Ericksen says they can't get a part let us know (click "Edit" and add it to this article). Also, if they do get the part for you, let us know that too!
- NOTE: Nissan USA is out of stock forever of the Sedan hose. But perhaps they can get the Coupe hose.
Wreckers, if you can find a 1200 in a wrecking yard
Friends with parts cars
Marine supply stores, for general fuel hose and filler hose. NAPA and other old-line auto parts store carry this generic fuel-rated hose also. Trimmed to length using the old filler hose as a guide. It is tough getting it to flex into shape, but can be done.
