I had the same problem. I put a fuel pressure regulator from the same aisle right after the pump set to 4 psi and it works great. I also like that if I get in a bind and have to replace it, it doesn't matter what psi the pump is.

You need to bend your float tab and that'll stop the gas from pouring out, Known in the Mikuni's

Its nothing bad its normal on the mukuni's some do it some don't i had to do mine, it just allows the float to put more pressure on the seat and seal it off and not keep letting fuel pour in the bowl.
