Excellent Walt, thanks.
Adapter list. So far we have:
Lycoming horizontal w/ 3/4" thread: Internal bypass, use 48110 or 48111 aircraft filter. Subject to field experience and possible test, Wix 51647 and equivalents, no bypass inside the filter.
Superior Air Parts: No internal bypass, use 48108 or 48109 aircraft filter. Many users report good operating experience with Wix 51515 and equivalents. The filter's internal bypass setting is a bit low for the aircraft application.
B&C BC700: No internal bypass, use 48108 or 48109 aircraft filter. Many users report good operating experience with Wix 51515 and equivalents (Napa Gold 1515 is common). The 51515's internal bypass setting (8 to 11 psi) is a bit low for the aircraft application.
Continental Titan: No internal bypass, use 48108 or 48109 aircraft filter, or Wix 51515 and equivalents. See above.
Airwolf Universal Lycoming Homebuilt Kit AFC-K001: No internal bypass, use 48108 or 48109 aircraft filter, or Wix 51515 and equivalents. See above.
