I'd like a larger tank on my 2012 WR450. Larger aftermarket tanks are expensive. Would it be possible to remove the Yamaha fuel pump from the tank and replace it with a small external fuel pump ? The tank volume would increase because the pump wouldn't be in it anymore. I'd mount the external fuel pump where the starter used to be. I removed mine. The other advantage would be that I could mount a filter between the tank and the external fuel pump. I love EFI, but I am worried about filtering dirt out of the fuel. ????
