What filler cap did you use?
I used this one,
I used a hole saw to drill the 1 1/4" hole. The above simply pushes in and pulls out.
You can also use an additional breather. Glue the grommet to the 1 1/4" hole in the cover, then the breather pushes in and pulls out.
Can it be paint thinner or it has to be lacquer thinner?
