Did your GATS Jar Fuel Tester lid crack? Mine broke after only 3 months of use. This seems to be a common problem and not wanting to buy another one just to have the same failure I figure a cheap 3d printed one would be great even if it doesn't last. I printed it in ABS and glued the halves together with Gorilla Epoxy.  Been using it heavily for over a month and it's been holding up fine for 100LL.  Given I'm not storing fuel in the jar for any period of time.

Reuse all the other components from your GATS jar: bottle, gasket and sump tool.

  • 3 Wall Loops (or enough that the sides are solid infill.)
  • ABS no supports
  • Epoxy - https://a.co/d/9pGKU8l
