Flew Cherokees for years, then switched to Cessna. Suggestion: dont throw away the insert thingy. Its for Cessnas. If you do, youll have to buy another as I did. Also make sure the yellow handle is tight, otherwise the screwdriver bit could fall out. Slick, simple, etc.

This is a great tool for six bucks. Makes testing fuel very easy. Flat and phillips screwdriver tips, works with various types of gascolators, fits easily into a flight bag, and sturdy. What's not to like?
