Dremel Stone #911
- The upper casting fuel inlet port seat must mate smoothly with fuel line compression ferrule. However, castings which have experienced a lot of rust will have seats that are pitted. These ports need to be lightly ground to remove the pits.
- A Dremel #911 stone, shown in the picture, works well as a grinding stone.
- Care must be taken to centrally position the stone, and only very lightly polish the seat.
