UD-3-F FUEL CAP W/FLAT ADAPTOR
Great part as per the catalogue.
Lancair 360 perfect fit and fantastic service again from Spruce
I used this “cap only” 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
Well made and easy to install
I like this fuel cap. It sits flush, is adjustable (for the tension of the latch) and seals well, Still, I was hesitating between 3 or 4 stars. Spare parts (O-rings) are available but the weakest part is the small pin that keeps the mechanism in place. This part alone is not available. Without it, nothing holds together. I had one failing while I was at a remote airport, Fortunately, i fou d someone over there willing to help and he sacrified a 1/16 drill bit that we broke to make a temporary pin and allow me to get back home. The pin should be offered as a spare part.
