Was it from one of the lower bowl-mounting screws? The washer gasket rings can be purchased separately without buying a complete kit. On my Holley I found that there is a ridge in the seat on the fuel bowl that imprints on the plastic washer surface. If the washer is reversed on the bolt when replacing it - it can seep fuel between the bolt head and the washer. I actually sanded mine flat again and they were fine to re-use but I bought some spare washer gaskets to keep on hand.
