Install Float Fuel Sending Units in QB Wings?

[JackinMichigan]

I just discovered that the sending units are RH and LH. Didn't know that. Now that I have that figured out, things are making a lot more sense.... I have a computer here in my workshop, and sometimes start firing out questions before my brain gets into gear...

Use the access cover as a template to make one out of plexi. You can then set everything up, being able to see in the tank with the sender installed. You can also drill a big hole in the plexi to allow you to move the sender through it's range of motion and watch to make sure all is good. When you have it like you like it, swap out the plexi with the real cover and you're good to go!

Great idea on the plexi. Thanks Java.

I used a borescope through the outlet after removing the screen. The float hit the rib, with the borescope I could tell how much to bend it. But first get a wrench into the hole and check the B nut on the vent. Find a short 9/16 to do that. A leak there will spoil your day on the first fill. Ask me how I know.

I tied a string to the end of the float and used that to insure that the float hit the top and bottom of the tank when held in position.
