CESSNA FUEL CAP C156003-0101

Purchased this item two years ago for my Cessna 150G. Works fine. The price at the time was $78, now it cost almost double that. If GA dies you can blame industry bandits for its demise.

Ive had these on our 1964 Cessna 172E for about 10 years now. Other than replacing the gaskets once (about to do again) they have needed nothing and continue to work well and even still look great!

These caps are the best quality available. They are vented so they drastically reduce the issue of uneven fuel usage when selector is on both on older Cessnas.
