Scale on strip inside is totally off. When the bottom of the tube is just touching fuel the tank has about 5 1/2 gallons in it not 0 gallons. Needs someone to actually calibrate scale with real tank

The plastic on this stick seems to be quite a bit more flimsy than other fuel dip sticks I have used. Also, the scale is a piece of paper stuck inside the tube, not printed on the tube itself. It does not seem very durable for the price. If it was less than $10 I could have given it more stars.

Q: Is this unit calibrated in US or Imperial gallons?

This is in US gallons.

Q: Will this fuel level indicator also work on other Citabria models (7ECA)?

Per the supplier: If it's a 19.5 gal tank it should work fine. If not, you could buy our universal fuel tube that you can calibrate yourself. Part number for the universal is 12-21260.
