I am into the final stretch of getting this airplane finished and I have some questions about the assembly of the original liquid glass tube fuel gauges. I have seen several other aircraft that must have had similar problems, so maybe it is just a common problem with the Cubs.
Any way, I noticed that when I started to install these gauges into the airplane nothing fits the way you think it should! The gauges don't line up with the holes in the new interior panels and they don't line up with the fittings that come out of the fuel tanks! I purchased new cork gaskets from Univair that go at each end of the glass tube as well as a new red indicator ball that float inside of the tube. I reused the bottom 90* fittings that screw into the gauge assembly and I purchased new AN fittings for the top of the gauges. I realize that you can screw these fittings into the gauge more to get the proper distance so that the holes in the interior panels will line up. But I had to really crank on those fittings to even get close---of course after doing that the cork gaskets were toast (smashed to the point that they would never seal correctly). Plus the glass tube now has a crack at one end.
What are my options???? This is a certified airplane so I am somewhat limited as to what I can do!
