    Fixed one of my leaks really fast. I should have purchased the whole fuel bowl kit though because there are still some other leaks. Then lines are leaking. Not the product or RiffRaff, that is on me.Just get the fuel bowl kit and spend a little more time and money. Great company thanks RiffRaff.
    God Bless!

    This set of o-rings hsve completely stopped my drain valve from leaking. A very easy fix at a fraction of the cost of a new drain valve.
