Hey guys new to greenhulk here but I've been over at the X for awhile. Anyway I picked up a 2003 GPR800 and this thing has been sitting for 3+ years. Finally got the pump off and it is corroded beyond belief I cant even get it seperated from the wear ring now with tons of heat so I figure I need a whole new pump. So my question is what pumps will bolt on to my 2003 GPR 800? Thanks in advance!
