i am having trouble with the fuel pump freezing in cold wet conditions. i ride in a lot of mud and water and at some points the fuel pump gets submerged. i think its time to go to a tm45. this is an awesome setup in the summer or somewhere it does not see alot of water. i never had any trouble untill i started submereging the fuel pump.and im sure it weighs half of a carb. maybe ill keep this setup for drags in the summer. its only 2 minutes to swap between this and a carb.
