Hey Kevin,A powered parachute guy showed me his "floatie" he made. I had just paid $5 for one of Bear's & placed it into my fuel sight line...
He used a plastic Bic pen cylinder. It fits loosely inside the standard 1/4" ID clear plastic fuel line.
Left the end w/ it's plug intact. Cut it off about 1/2" in length.
He sprayed red paint all over it, even on the end w/ the Bic plug.
Then he coated some clear automotive sealer that is gasoline resistent or impervious all over his cheap floatie, including plugging the other, open end. Then he let it dry.
I asked him what about if the sealer broke down w/ it being submerged in fuel in the sight gauge.
He laughed @ me, stating that he checks it on his pre-flight. If it ever appears to be breaking down, he'll replace it.
That replacement cost?
Possibly one cent worth of paint & sealer!
Thanks Jeff,The Grumman AA1 series aircraft use similar balls in there fuel site gages.
That’s interesting in that I used to own a Grumman American TR-2 (AA1A).
I don’t remember having that kind of sight tube. But this was back in the early Seventies. Whole lot of things I don’t remember from that far back.
thanks again. I’ll look into these.
Thanks Kevin. That makes more sense.Scott: It was the outside cylinder, not the small tube that the ink is held in. His looked a shade larger in diameter than Bear Perkin's, which looked to me to be only a cylindrical piece of small, red plastic, rounded @ both ends.
I realized I wrote 1/4" clear tubing. Afterwards, when thinking about it, it had to be a tad larger in ID, in order for that homemade piece to fit...maybe 3/8"?
His looked rougher (probably due to that sealer he coated it w/) & it was a darker red color than Bear P's, but the price was certainly better!
Do you still have your Dominator? I saw you @ Mentone in 2012, when you had it for sale.Thanks Kevin. That makes more sense.
right now I have 1/4” ID tubing. May have to go with the bigger stuff to make that work.
