Water is a normal byproduct of combustion. You need to figure out what this 
fluid really is. Keep in mind that even if it is mostly water, it will smell 
strongly of gas. Collect some of it in a glass and then add a bit of water. Gas 
won't mix with water.

It is normal for a generator system voltage to fall off at low RPMs.

4 tanks should pretty much clear your tank of water, but if there is rust in the 
tank or FI parts this will persist for a long time. You may need to 
replace/clean the filter(s). Pull out the gas gauge sender and look down there 
with a flashlight. How clean does it look?
