Fuel Quantity Measuring Device

Post by meowmeow »

Hi, I'm in need of a fuel measuring device that looks like in this picture - apparently it's required equipment for whatever bizarre reason, but our used plane didn't come with it, or someone took it.

Part # is D60-2817-90-00_01

This is the only method of physically measuring the fuel remaining on board. Probably only available directly from Diamond I would suggest.

Does anyone have it? In my 4 years flying DA42 I've never seen this device and I don't know any owner/operator who owns it.

I have one (or at least a similar device) for my 40. Prone to leaks and practically useless, but I keep it in the back tube anyway.

I have one, but don't keep it in the airplane. Too easily broken, and someone mentioned that they were quite expensive to replace...

I had one for the eleven years I had my DA40. The glass tube shattered almost immediately, but I replaced it with a clear plastic tube. I kept it in the plane.

There is one in my DA42 as well.

The dumb thing is on the required equipment list. If you want to conform to this find some kind of a hard case to put it in and store it away where it won't get damaged. I can figure fuel remaining based a combination of hours at last fill (which I record) vs hours flown and the fuel gauges, which are at least as accurate as this thing. If I were a little less lazy, I could also use the fuel totalizer.

With the plane level, the "V" shape fits on to the front of the wing at the point where there is a indented dot directly in front of the underwing fuel drain. Use the end of the hose to press into the fuel drain to cause fuel to flow. The law of cylinders will do the rest. Works on both wings.

Most people replace the glass cylinder with a plastic one to eliminate breakage.

I admit to being surprised, though, that these are unknown. They've been on every Diamond I've seen for two decades. It is the only non-electric way to know what's actually in the tanks since dipsticks won't work. (And much easier than what I had to before where we had to create one's own dipstick on my old Decathlons, etc.)

LOL. I said "efficiently." I was taught how to use them in my first Diamond checkout 18 years ago and had to teach it a few times. Can be done, but it would be helpful to have three hands :D
