Reviews

I used this âcap onlyâ to rebuild a 18 year old cap on my F1 Rocket. The old cap over center feel was getting a bit numb. The new parts fit beautifully and now my caps work like new. A 5 minute job, should have done this sooner.

Jim, I needed the Fuel Cap before the July 4 holiday weekend. Called Josh, he handled the sale and it arrived 2 days later! Very pleased with the response from your staff, especially Josh who got the job done!!! I was able to take advantage of the weekend and fly my aircraft!!!! Kudos to Aircraft Spruce, Josh and your staff who made my weekend! Thanks, John

You can use either 05-02146 (USHER O-RING 2-325 LARGE) or 05-02147 (USHER O-RING 2-012 SMALL), which can be found in the "Accessories" tab.

There is no functional difference. They are used in two different spots of the fuel cap. Both should be replaced annually or as needed. Please see the "Tech Sheet" tab for complete details of where each is used.

Q: What type of allow is the flange of these Usher fuel caps made of?

Per the supplier: It is 6061 alloy.

The function of the contoured adapter is the shape of the ring that the cap will fit into. The contoured ring has a small flange to it compared to the flat adapter which has a flat ring.

Yes, these are compatible with diesel and jet fuel.

Q: How much do the 05-01061 & 05-01062 Fuel Caps w/Adaptors weigh? I cannot find a weight on the spec sheet for each assembly.

Each weighs .375 lbs

Q: Can I purchase just the cap without the adapter?

Yes, but this is a special order. Please contact sales department for pricing and lead time details.
