Sunday at the Hangar

It was a nice day to be here. Sunny and about 80 degrees.

Shoulder Harnesses
Windshield end piece. I ordered them from Univair as I didn’t have any originals.
The emblem from Fritz’s Womack/Murray Sport and from his coveralls. And since most if not all Stinsons seem to have a name, I think Fritz would be appropriate for this one.

Sunday at the Hangar

We pushed the Stinson out to clean the hangar floor. Took advantage of it by taking some photos. I should have dusted and polished it first.

Started the process of fitting the windshield.

My best helper.
Setting it up and marking it for trimming.

Fuel Indicating System

It’s a simple, decades old system that works well. When it works. Some say it’s from General Motors, but the sending unit is a Ford unit. I’m told it’s from a 1938 Ford truck and you can buy the sending unit off a Ford Restoration website for around $43.00 (Part #: 99A-9275).

The Stinson fuel sending unit mounts on the bottom of the fuel tank while the Ford sending unit mounts on the top of the tank. So full fuel in the Ford means low resistance from the sending unit .

In the Stinson, it’s opposite due the sending being mounted upside down. Low or a short indicates empty and high resistance indicates fuel fuel.

The Ford sending unit linked above shows 125-135 Empty, 17-19 Full, so turning that unit up-side-down you will have 17-19 Empty and 125-135 Full. Seems about right with this Stinson.

Some Stinson webpages show it wrong, but Larry Wheelock’s post is correct. At least for this Stinson , this is how it works.

The gauge has three posts. Two are on the right side of the gauge as you view from the rear of the gauge and one post on the left. I’ve read that one post is for 6v systems and one for 12v systems. I connected it to the bottom post for 12v.

Rear view of the fuel and ammeter gauges. Fuel gauge is on the right. Ammeter is on the left. Wire 31 is from the C/B and 32 goes to the Fuel Selector Switch center terminal. The nuts on the gauge have not been installed when the photo was taken.
Front view of the fuel and ammeter gauges. The gauge is off a bit as this should indicate empty.
This should indicate a half tank.
This should be a full tank, but the pointer goes to the stop.
Switching between the two tanks shows the same empty indication. The gauge is off for both sides.
My schematic for this Stinson’s fuel indication system.
