Flop tube

26 Jun 2004 Flop tube

I’m working on putting in the flop tube into the right wing. Now I found a little problem. Why is the ID of the aeroquip hose less than 1/4″ when it should be 3/8″?

Flop tube aeroquip hose on the left, normal AN-6 fitting on the right. Notice the size difference.

Here is the brass end of the flop tube, and the aeroquip hose. The red fittings seem to have a very small inside diameter on the aeroquip.
