Thank you for your reply. the bulb gets hard when I prime it to start, when I run it at higher speed it gets soft and the motor dies after just a little ways. when I prime it again it's as though it had no fuel at all in the line. I switched tanks and hoses but it still does it. it will idle ok, but it does get hot. it seems to be peeing out enough water, it's just hot to the touch, almost too hot to touch for more than a second.
