So I have 2008 yfz450 478cc pump gas piston and hot rods crank, i am wanting to make it fuel injected i know I'll need the throttle body, ecu, wiring, the new battery box, fuel pump, and grab bar but issue is I dont want to swap the plastics so I can do the different fuel tank any ideas on how to modify the stock carb model yfz450 gas tank so I can install a fuel pump. I have a good amount of mechanical experience but I'd prefer not to mess it up maybe use a yz450f fuel pump since they are upside down? Any ideas are greatly appreciated alot.
