Retrofit Fuel caps
These retrofits go flush into the existing wing, do not leak, do not fall off and are ‘finger friendly’. I think you, and your co-pilots, will like them.
Available from Vans, as the retrofit cap, and from ‘Spruce as 05-01006.
So far as I know Vans are the last manufacturer to use the Usher cap.
You may see a similar cap offered elsewhere. He assures me that it is not a copy, but I suppose I feel flattered as well as cross. as you will have noticed we now offer exquisite fuel valves that are novel, not a copy of anything else on the market.
