Hey guys FYI:
im in the US and i have a 95 tracker, i orginally bought the universal Filler hose made by Gates at opening of 1.5 inch, i removed the filler neck and tried to install the 1.5 inch hose, but was too smalli tried to dip the hose in boiling water but would not fit properlpy, took it back and got the 1 3/4 hose which did fit ok was not extremely tight, so i secured it with the clamps. prolbem solved.
Hint: if you drop the tank be sure to point the screw on the clamp to the bottom as to access it from bottom, since there is not a lot of room for hands and ratchets above.
