I have a 2003 arctic cat zl 600 efi. The fuel pump went out on it so i bought a new one and that one went out too. I looked online and alot of people are saying that the in-tank pickups get clogged, but i was seeing if anyone else had any ideas what could be killing the pump. It didn't happen when i was ridding it. I would hit the kill switch and i couldn't get it start again. I was also wondering if runing premium in it would kill the fuel pump?
