The high precision and easy to operate mechanism is very secure and non vented. They are designed to keep the fuel in and the water out. The lock is there to ensure that your tank is free from contaminants. Aero caps are used on Adam, CAP, Cirrus, Diamond, Lancair Columbia, Lancair kits, Nemesis, Vans, Velocity and many more aircraft.

Q&A

Q: Could you please tell me the size of the hose neck on Part # 05-28653?

Either 2" or 2-1/2" I.D. hose can be used on the 05-28653 hose neck.

Q: What is the difference between the filler neck of 05-28653 and the hose fitting of 05-28659? Do they come with the back flange and mounting screws?

The only difference is the 05-28653 has a locking cap, and the 05-28659 has a non-locking cap. They do come with mounting hardware (screws & nuts), cork gasket, but not a back flange.

Q: What is the difference between Part #'s 05-28654 and 05-02650?

They are two different size caps. In short, the 05-28654 is a much smaller diameter cap than the 05-02650.

Q: What is the size of the entire ring in the 12 hole set? P/N 05-00045 A512L

This would have a 5.47" Outside Diameter and a 3.27" Inside Diameter.

Q: How much does this Aero Fuel Cap (part # 05-00045) weigh?

The cap itself weighs 0.54 LB. The entire assembly including bolts, keys, gasket, and mounting ring is approx 1 LB.

These caps are priced and sold as each.
