Latch And Post For UD-3 Gas Cap

The original gas caps on my RV-6A woul not completely latch closed. The bottom of the latch had worn. I added the two new o-rings and ss washer to complete the rebuild. Works perfectly!

Latch And Post For UD-3 Gas Cap

Worked perfectly for the fuel caps for an RV-10. Miine had worn and would no longer snap into place when closing. The latch would want to sit slightly proud above the cap. Thought I would have to replace the whole cap until finding this part. Worked PERFECT!

UD-3 Gas Cap

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

Nice quality cap. Perfect drop-in fit for my RV-6. The only thing I dont like about this cap is that the cut-out for your finger it too small. I just cant seem to get these caps open without using a key or some other tool to pop the tab up.

UD-3 Gas Cap

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.
