    Experimental or certified? If experimental, I used Larry Bauer for mine:

    Dakota Cub, better visibility and they use o'rings which are easily replaceable instead of cork gaskets which require removing wing root covers, hose, etc. http://dakotacub.wordpress.com/2010/...-sight-gauges/

    Steve, I have a set of each, which way is up for Dakota Cub and Piper? Seems to me that you should turn the Piper ones over from what you have shown to show fuel down to 0? And do you have a part number / source for the sleeve? And does the 'restricted' elbow go on the bottom? Don

    best smaller part down.... not necessarily right...

    restrictor should be in BOTH incase of glass breakage.....

    OK found out, the thick bolt goes on the bottom on the Dakota Cub fuel gauge. Makes sense that you can then remove the glass to replace O-rings without any further dissembly. I guess this logic could apply to the piper gauge too, but then the visibility at low fuel levels will be more restricted. There are no restrictors in the DC fuel gauge fittings. Don

    Dakota cub builds the restrictors into there tanks. they weld the fitting on to the tank and drill a small hole through the inside of the fitting into the tank, that way if the fitting happens to break off the gas still comes out slower.

    The factory gauges had the short end on the bottom along with the restricter.

    This is from the production line in the mid 1070s. The red elbow has the restrictor and the end with the flats is shorter that the end without for better visibility when low on fuel.

    Is it possible to install a sight gauge in a J3 wing tank?

    I think Clarence Witte had an STC for it. Check with the new owner of his STCs, Scoot Air. http://www.scootairllc.com/website/wingtank.htm

    Found my list, They own all of these STCs but not sure that they have approval on all of them as of yet.

    SA1496GL J-3 12 Gallon wing tank
    SA00715CH Sight gauge for above tank
    SA01334CH J-5 19 gallon tank
    SA00805CH PA-12/-14 19 gallon tank
    SA01333CH PA-12 24 gallon tank
    SA1765GL J-3/PA-11 fixed and swing engine mounts
    SA01104CH PA-12,-14 swing engine mount

    Mike, Any reason these sight tubes won’t work with the Dakota 24gal tanks?
    STC states 30.5 Atlee tanks

    Not sure that you can see thru the Dakota Cub gauge, although they are heads and shoulders above the Piper gauge with one exception if you cannot. Note how the fuel refracts the level lines behind the gauge when you can see thru it making it easy to confirm fuel level and/or that there is actually fuel in there. One member had an incident awhile ago around this issue and may offer his opinion based upon a well learned lesson, Jim

    Make sure the 'little red ball' is installed and floats on the fuel. That's the original design and it works much better than looking for the fuel line itself.

    Thanks for the heads up on the red cork ball. Had these on my Grumman but didn’t realize the Piper PA used the cork too

    Do the Dakota gages fit the port spacing on Atlee 30.5 tanks?

    Gordon I'd like to know that as well!

    I have the Atlee 30 Gal tanks on my certified cub, and the sight gages (Cubcrafters I think) on there look pretty but are horrible because the float balls are in the bottom metal area when I still have 15 gal left a side........I also run a totalizer but not seeing any fuel in the sight gages is unnerving to me.

    I've been considering the Atlee Tygothane tubes because they dont have the metal on the top and bottom......anyone using/liking those?? They are very spendy for what they appear to be but they give you the visibility down low!

    Mike, thats great to know.......! Have you installed the large AD tanks?

    To be clear....(Sorry)....So when you have 5 gallons or less in the 30.5gal tanks and Tygon guages, you can see that level easily? (in level condition, I have lower expectation in 3 point)

    If thats the case I'll order some asap....!!

    I have the Atlee sight gages, which I installed with the Atlee tanks in 2011. When they show empty they are telling the truth. They work great, but get yellow and more opaque with time. I cant help but wonder if they are also hardening.

    It was a poor choice of background color. but the gauges work great. Available from ACE aircraft supply.

    I have a new set of these which did not fit to my satisfaction. Name:  medium_51c854f748e2d1372083447.jpg

    Has been an age old problem since the early under wing sight gauges..... My old 12 guages will show only 3/4 per side after 30 mins of flight filled right to covers.... When the ball is disapearing into bottom aluminum
    on either side you will struggle to get 10 gals in the tank; so when the guages say I am out I have well over 2hrs of fuel left. So when most folks would call it unsafe to take off you have approx 18gals onboard.

    We threw the set of those in the trash that came from back country. Poor copy.... very hard to make not leak. We went with Atlee gauges

    Hi Mike- I was just reading the Atlee STC materials and depending on how you read it, it sort of looks like you can only use those guages on the 30.5 Gal tanks??? Take a look....its not well written IMHO.
    My guess is that since the guages are longer/taller it may cause issues....
    Obviously this would apply only to certified birds......on experimental there may be pros and cons.
