|Real fuel cap gasket. RG-2551|
This fits a 1948 170, not an A or B model. The catalog is correct.
These are the correct size for 1948 Model 170, but these were not thick enough and did not seal. They should have been about twice the thickness.
This is listed as a fuel cap gasket for a Cessna 170, but the OD is listed as 4+ inches, while a Cessna 170 fuel cap OD is only 2-7/16
