I used this âÄúcap onlyâÄĚ 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
