Silly me, I think it is really 1.0gpf/3.8Lpf
Professor Davidson from the Department of Physics & Astronomy, University of Manitoba explains: "In Canada, if we use gallons at all, we use the British gallon which is defined in a logical way: 1 gallon of water weighs 10 pounds (not very metric, but logical at least). The American gallon is defined as 3.786 litres. There is probably a logical reason for the American gallon as well, but I am not aware of it. The problem is to convert from one to the other. We can proceed by finding the mass of each gallon: A Canadian gallon of water weighs 10 lb which is the same as 4.535 kg. The American gallon is equivalent to 3.786 litres, and since 1 litre of water weighs 1 kg, an American gallon of water weighs 3.786 kg. Obviously, the Canadian gallon is the larger. The ratio is 1 gal(CAN) = 4.535 / 3.786 = 1.198 gal (US). Rounding this off to 3 significant figures, we find 1 gal(CAN) = 1.20 gal(US)."
