The Fa has an automatic transmission the Fe has essentially the manual transmission that is operated electronically with 2 buttons instead of a foot pedal.
I don't think there is much difference between the 2. The TP sensor is mounted slightly different but works fine and the price is different. I'm sure you'll have no problem using it.I ordered a new carburetor for my 2009 Honda foreman and noticed i got the fa one and i have a fe wanted to know what the difference is and if it matters?
