I just completed Fuel Filter SB dated 10/25/2019. I called CC but no 62 micron filters are available. They are sold out at Spruce an all other venders in USA at this time. So I contacted Andair in England directly. Sure they have them! I got one one week later. Installation - no problem.

Good news! I used to have significant fuel pressure sag at full throttle without electric fuel pump on. Not any more. Despite Andair's claim of "negligible pressure drop" with the 10 micron filter - flow was certainly limited with only the mechanical fuel pump.

If you need to comply with SK-SB003 contact Andair. They have 62 micron filters available.
