Cameron:
I have a choice of 2 inspection holes to cut. Don't want to cut any more than I have to.
In relation to the filler opening, on top, where are senders, laterally? Outboard or inboard?
Looking at the tank drawing, I see no indication. That is, a view from front or rear.

I am glad to hear inspection hole large enough! I hope my rings were placed accordingly!

Zeke,
The sending units are on the bottom of the fuel tanks. If I remember correctly, the sending units are outboard and aft of the filler caps. The sending units are sort of in the middle of the tank.

If you take a look at drawing 44253, it shows the locations of all of the inspection covers. My guess, based on my memory and if I can read the drawing is that it is the one that is 16 7/8" aft of the front spar and 24 3/4" outboard of the wing root.

Cameron,
Thanks for all the help. I just got my senders in and need to figure out how to reverse the resistance. It looks like the 385C-F senders are made to hang in top of a tank. So, Full and empty resistance values reversed. Is there an easy way to change this?

I am still fighting my fuel sender battle. The inspection holes weren't placed where they should be and I will have to patch the wings. Not happy.
I would love to see how you bent your float arms. I pulled old senders (they were different) and shaped my float arms to wrap 180 degrees so full and empty are in right place. However, this moves the float "arc" or sweep aft where there is less vertical space. I am thinking of another 90-degree bend to put float slightly forward, but that shortens the sweep. I believe it will be close enough for decent representation of amount in tranks.
