How can I remove the oil pump etc

 

im assuming this is a 2 stroke? are you trying to do away with the whole assembly and mix the gas your self or service it

 

Get rid of it so I can run pre mix

 

if it were me i would unhook the pump from the wire harness if you can and or remove the fuse if there is a fuse for it if not i would unplug it an plug the hose that goes to the carb from the oil container and call it a day that way if u wanna hook it back up it there.
