I wanted to let you know that I have already sold out of the fuel cap kits. I have ordered more of the large o-rings, and should have them next week. I can continue to take orders, but shipment will be delayed.
In addition, I want to let you know that I also have the correct o-rings for the under- wing sump fuel drains. They will be $2 per pair shipped separately (postage included), or $1 per pair if included in with another order, for as long as my low-cost stock holds out.
