It looks like there is a little pin hole right in the center of my fuel pump. Is it supposed to be there because I'm having trouble with it, the only time I've had trouble with it was when the fuel pump went under water. One time it got sand on it and bike wouldn't run until I blew the sand off the pump. Next time it appeared to have sucked water in and got in carb and stopped bike dead, wouldn't run till I drained bowl. So it seems like it needs that pin hole to work right but there is no way to hook a vent line to it to run it up high. Also has anyone swapped it out for an electric one?
