The FU engine came on the "GFU", "FU" and "MPG" cars (USA-market B210 and B310 fuel economy champion models). F means Five-speed. G means GX trim (not dual carb). U means USA (FEDERAL, except California). They got up to 50 mpg (21 km/liter).
1977 B-210 50 MPG (US gallon = 3.78 liter)

B210
The FU model was a B210 Coupe fitted with A14 engine and 63a Five-speed transmission. The 5-speed was introduced to USA models from 1976-1/2, and to Canada models for 1977. 65 HP A14 with round ports.
5-speed models were only available in Coupe body style. All 5-speed models were fitted with FU engine. So for America, 5-speed was for fuel-economy, not performance option.
