Schllc Posted March 7, 2021 Report Posted March 7, 2021 Does anyone know where these can be sourced and if they can be installed? I’m going to have an older ovation, I’m in the process of acquiring, painted in the near future and was going to reseal tanks prior. I’d love to incorporate the new caps. If you have not had the pleasure of using them, you should give them a look. They are so much nicer that those two pound bricks we have, and never misalign the way the old ones had a tendancy to do.

Hank Posted March 7, 2021 Report Posted March 7, 2021 Do you have any pictures? Ultras in the wild are a rare breed, I can go years between sightings. Quote
Schllc Posted March 7, 2021 Author Report Posted March 7, 2021 I owned one so I can attest to their existence! 2 Quote
Davidv Posted March 7, 2021 Report Posted March 7, 2021 @Schllc They really are great caps, I couldn't believe how light they are the first time I picked one up. The only downside I could see is that the hole is a little smaller which could be a problem when you're filling a plane with Monroy tanks (to see the fuel level). Did you ever have this issue? When I fill mine with the regular cap I need to find the exact perfect pressure on the pump handle to keep it from bubbling over. Quote
Schllc Posted March 7, 2021 Author Report Posted March 7, 2021 I don’t recall having a problem on the ultra, but obviously didn’t have the Monroe tanks. they are a dramatic improvement to the old caps that felt like lead. Where can the caps and items needed for install be acquired? Is this an stc, or just a field approval? Quote
Davidv Posted March 7, 2021 Report Posted March 7, 2021 That's an interesting question since I'm not sure how the cap body interacts with the wing. This is an R you are acquiring? If so, I doubt any approval is necessary if the later non-U ovations were fitted with the cap. I'm assuming the later R's have the cap since I know they are at least on Acclaims from the 2007-2008 era going forward. I'll ask the team tomorrow morning and shoot you a text. I'd also be curious if they add any bit of drag whatsoever since they are raised rather than flush with the wing. I'm sure probably knot (couldn't resist), but I'll ask. Quote
Schllc Posted March 7, 2021 Author Report Posted March 7, 2021 They aren’t on all the 2007’s. I’ve had two that didn’t have the new style caps Quote
hammdo Posted March 7, 2021 Report Posted March 7, 2021 Sabremech did these on the bird I bought from him... 337 -Don Quote
Schllc Posted March 7, 2021 Author Report Posted March 7, 2021 I saw that, he is emailing me the paperwork details. It’s been suggested, that since other long bodies have them installed it will be a simpler process. I’ll post the results when the time comes. Quote
carusoam Posted March 7, 2021 Report Posted March 7, 2021 Changing fuel cap style is as easy a process as it can get... The fuel neck, the part the cap fits in, is mounted in an access panel... So swapping out the panel is a straight forward, known process... Cutting a smaller hole is best done with an uncut access panel... If it is a Mooney part being used on another Mooney, the paperwork just got as simple as possible... Buying all of the parts... 1) Seeing if Mooney can be the supplier best for a turn key approach... panel, neck, cap, and paperwork... all assembled. 2) David/sabremech has great pictures of how he did it... Sabremech also has the complete mod / paperwork skills... if/when required... 3) We have a fuel cap guy around here as well... very familiar with all the variations of fuel caps... The small, very flush, cap... looks great... Finding a pic of one would be great too... to be sure we are all talking about the same device... Let us know if you need help finding these people... Best regards, -a- Quote
Niko182 Posted March 7, 2021 Report Posted March 7, 2021 The guy that owns the ultra 2 rows down from me isnt at SNA right now. If hes back when I get back later today, i'll snap some shots of the fuel caps. Quote
Seth Posted March 8, 2021 Report Posted March 8, 2021 Are they the same as the current Cirrus caps? -Seth Quote
Seth Posted March 8, 2021 Report Posted March 8, 2021 (edited) These are the Cirrus fuel caps. Same for new Mooney? If so it's a 300 series fuel cap - forget the company name. Very lightweight and maybe 2 - 2.5 inches diameter. Edited March 8, 2021 by Seth Quote
Cruiser Posted March 9, 2021 Report Posted March 9, 2021 Is the purpose of the new small diameter fuel caps design to prevent misfuelling with the larger Jet-A nozzles ? Quote
Yetti Posted March 9, 2021 Report Posted March 9, 2021 Then the cooler thing to do instead of sheet metal work to make the hole smaller... Would to make a larger flange that fits the existing sheetmetal holes that accepts the new smaller cap. 1 Quote

Would to make a larger flange that fits the existing sheetmetal holes that accepts the new smaller cap. Here’s what I did on my old C. No need to drill another hole as this gets rid of the dissimilar metals and has the cap flush with the panel. Not that difficult to do. David 2 Quote
