Do you mean you have installed the PVC leading edge from a IV onto a
II? Or is there some other leading edge treatment for a II I am not
aware of? (I thought they used the aluminum tube as the leading edge.)

A reasonable concern, considering how much flex I see when I fly. If
I were you I would definitely hang the plane by the tips before
covering and jump up and down on the fuselage while observing the top
skin. It should be pretty obvious if there's going to be a problem.

Well the gascolator won't do much, and certainly won't pick up any
water, since the height of the valve precludes any water reaching it
from the tanks. You also didn't mention filters, which are a good
idea and a topic of much previous discussion, (hint, hint,) here. I
have been flying a similar configuration 300 hours without any aux
pump, and with a race car filter. I do, however, rebuild the fuel
pump every year.
