How do you check the C172 fuel tank cap vent
Asked by: cmpt7 4681 views Aircraft Systems, General Aviation
On the C172R/S pre-flight inspection checklist it says to make sure the vent on the fuel tank cap is unobstructed. Where is the vent located on the cap and what does it look like? Also does it serve the same purpose as the long tube-like vent that protrudes from the left wing?
