Here is one of the things people complain about the most. Assembling the fuel tanks. It's kind of a bummer, but it's not the end of the world. Just super duper messy. My least favorite texture is sticky, so you can imagine how much fun I'm having. Oh well - gotta get it done. First things first, you've got some items to attach to this outboard rib. One of those things is the nutplates for the fuel level senders. The standard thing is fuel floats - but I just couldn't bring myself to live with the status quo. I had capacitive senders made by Skysports, and they look pretty good. They attach with AN3 bolts though, so I needed to drill for the larger nutplates. No big deal, just a number 12 (i think that's what it was) for the center hole of the nutplate. Now you start to rivet stuff on. Nutplates for the senders, anti-rotation plate for the vent fitting, and the finger strainer flange - basically the fuel pickup.There's also some tooling holes that just need to be filled. The directions have you making a cover piece out of scrap, and drilling holes, and riveting. I had purchased a huge rivet assortment awhile back, and i just put in a fat rivet. I actually dimpled for a 426 flush head rivet, because i didn't have the correct die for a 470 universal head rivet. worked well though...

Then its on to the tank stiffeners. Bethany loads the prosealed rivets in, then we flip it over and back-rivet. Pretty straightforward. It's possible that I''m going overboard with the proseal, but I just don't want the thing to leak after we're done with them. So after the stiffeners are riveted, I'm here smoothing out the proseal around each stiffener so that there's a good seal. A fun part was installing the fuel tank filler flange. We went with the locking aftermarket caps, and I'm glad we did. It took a bit of work to fit them (done earlier during tank pre-assembly) but the result is excellent.Also did the fuel drain flange here. Then we start to get the ribs into the skin. The deal is that you have to seal every mating surface with proseal, and you goop up every rivet with the stuff too. If you're not familiar with proseal, it's a two part tank sealer that has a working time of an hour or so. You get into a groove though... mix a batch, rivet rivet rivet, get through a little section, then mix a new batch and continue. Not too bad. You just have to constantly clean your tools. Bethany goops up the rivets...Then she installs them...Then I rivet them.
