KX450F fuel pump: interchangeable?

[FrankV]

Hi,

 

Does anyone know if the fuel pumps from the several model years are interchangeable? I think so, as the OEM numbers only slightly differ, but I'm not sure:

 

2009: 49040-0037

2010: 49040-0037

2011: 49040-0048

2012: 49040-0711

2013: 49040-0711

2014: 49040-0711

 

Thanks ?

2009 2011 fit and 2012 till now fit. Bolt patterns are the same but in 2012 the orientation of the pump changed.

Thanks. So the 2012 and newer pumps will not fit the 2009-2011 tank due to the renewed orientation?

Exactly, it will bolt into the tank but after that the fuel hose is in the wrong place and won't fit

Perfect - thanks a lot ?
