As advertised, fits perfect.

Great for preflight planning, but as previously mentioned it a bit overpriced for what it is.

In essence a straw with a piece of demarked paper inside. How long will it last - we will see. Had a generic one before that had marks edged in outside of plastic straw. Yes, had to calibrate it but would have lasted forever had it not been left at a fuel island.

Exactly what I was looking for. If you use ForeFlight weight and balance on a Cherokee, this allows more precise calculation by entering gallons remaining in each tank.

This is one of my favourite purchases Ive made for my Warrior. Its been a lot more use than things Ive paid 10× or even 100× as much for. To go from 4 to 5 stars, they could attach something to the top (a wrist lanyard, maybe) to keep it from slipping down into the tank if your not paying attention. Thats never happened to me -- it sticks out far enough that you can keep a good grip -- but its always on my mind.

I bought this for my Piper Cherokee 140 to verify what fuel tank quantity is on my airplane. My OM is for a 150, 160 & 180 Cherokee and my Qref Book is for a Cherokee 140. There are specification differences and this tool verified the size of my tank.

Seems to be accurate and easy to us. Way over priced!

Q: Before I order I want to be certain this is what I think it is. Question: Is this fuel dip stick for a PA-28? Specifically, will it be accurate for my Cherokee 140?

This is the fuel level indicator for the PA-28 Cherokee. As long as the tank capacity is 25 gallons, it will work correctly.

Q: Are these direct fuel level indicators for the Piper PA-28 marked in US gallons and/or litres?

These are marked in gallons only.

Q: Are the gallons marked on the tube as well as on the aluminium scale?

No, the gallons are only marked on the aluminum scale.

Q: Is this direct fuel level indicator for the 25 gallon or 36 gallon tank?

This indicator is for the 25 gallon total tank.

Q: Where on the fuel tank opening do you read from? For? Aft? Middle?

The fuel cap is removed and the fuel gauge is inserted at any location of the filler neck. Generally is read from the Middle.
