m20f fuel stick calibration

[garysuperpilot]

Does anyone have a "chart" so I can make a my own stick type gauge to visually check the fuel in my tanks? I know where they are at full, at 25 gallons, (looking at the metal tabs), and figured out when the fuel is just dry under the fuel cap(about 9 gallons remaining). I have a universal tube gauge but does anyone with an f model 64 gallon tank have inches as relates to gallons. I do have a fuel flow gauge which is probably the most accurate, but I'm used to sticking the tanks. Old habits die hard.

Why not just run it nearly dry and then make the marks as you fill it 2 gallons at a time? Some say actually running it dry is no big deal and everyone should do it once. I suspect that's true but flinch at the thought. Stick it to em.

I ran acoss the numbers online a long time ago, I even made up a stick to dip the tanks on my C model but after using it a few time I relized that since i am the only one flying my plane I know how much fuel i left in the tank, or it was full so the stick just sits in my box of goodies in the baggage compartment. I will look around and see if i can find those numbers again and post them for you..

I think this was talked about. Do a search for "fuel tank dipstick measurements" Its for the stock 52 gal tanks. 7-14-10 was the date on the post. Knute made the post with a nice little inch per gallon chart.

You don't really need to run it dry. You can run it dry to the point the dipstick sees no fuel, but there is still around 10 gallons left (in the J at least). The 25 gallon mark is a good absolute calibration point as you fill 2 or 5 gallons at a time and build the curve. I use the same graph for the left and right tanks as the difference is slight.

I use the "Universal Fuel Hawk" tube on my '67F with 64gal tanks and have it calibrated in 10 liter increments on the chart that comes with it. I can give you those, if that would help. You can just convert it gallons.

I made my own stick for my 67 C. Drained the tanks completely (I was replacing the fuel senders so I had to do it anyways). Then called the fuel truck from the FBO and had him add 1 gallon at a time while I documented the fuel levels. Even though my JPI 730 keeps very accurate track of remaining fuel (within 1 to 1.5 gallons) I don't trust anything but the fuel stick. This is really easy to do. Just get one tank as low as you feel comfortable, then get a couple of gas cans and drain the rest by removing the fuel drain valve under the wing.

I found some info for the 50 gallon tanks but not the 64 gallon tanks. I will take your suggestions and make measurements as I fill the tanks a gallon or two at a time. At my airport the line guys get a little lonely anyway so I'm sure they'll be happy to help. Love our "new " mooney and thanks.

I have a dipstick for my '67 F that is just 10 n-numbers away from yours. I have the standard 64 gallon wet-wing tanks. We made it over 15 years ago, and it seems to be pretty accurate for our use. I can send you the measurements later this week.  There is no guarantee as to the suitability of the measurements for your intended use.

Sounds good. Should be pretty close being our birds were born so close to each other. Thanks
