[Big hammer]

Jim I found the same thing about the 30-31 caps letting water into my gas tank, after washing my Tudor and a drive to dry her off. She began spitting and sputtering and then died in one of the busiest intersections around town. No separator and after a fire drill of me checking things I found if I over choked her she would run poor, drove about 3 blocks home and put some gas line drier in the tank. Again went for a nice test drive !!!
