m50 fuel pump
 

hi
can any one advise ,
issues with my fuel
bike not getting correct fuel to enable it
to run long before it cuts out ,my fuel pump set up
is code 15100 39G10
uc T30su25
i have got a complete spare but different codes on the pump
they are
15100 39 G00
uc T30 su20
they look exactly the same
but i am not sure if it will work ok wirh it having different part numbers
i was going to fit it and try but concerns over incorrect fuel being sent from pump regulator to the injectors and what damage it could do
my bike is a 2009 model
the spare pump set up i have is from a 2005 model
information i have found so far is up to a 2009 model bike some say it will fit up to that year and some have my parts code on and fuel regulators all seem to have different psi
i am not even sure what is fitted on my bike
