You have it backwards. If the float or the wiper gets stuck reading high that's when the right side will go below 1.4.

Only two reasons the right side will go to zero:

1) there is actually no fuel in the left side and siphon jet is working

2) siphon jet is not working (usually due to o-ring failure)

1a) you may have a reading of yes fuel on the left but not actually have any fuel due to the sending unit not reading correctly

Symptoms of that occurring:

1) fill the tank and reads 3/4 tank
2) near empty tank the distance to empty doesn't change
3) the buffered and non buffered tank total with test six are quite different.
4) reset with test 21 and the fuel amount changed drastically
