Rob,
We use the blue urethane inside the tank and for the vents. We also use the RANS fuel tank fittings, which are aluminum with a captive surface O-ring, so they can't rot like the rubber inserts that Titan supplies. They are far superior, and are now the only fuel tank fitting we will use on plastic tanks. They require a 1/8"NPT male fitting on each one once installed to connect the hose to.

Subject: [Titanaircraft] Fuel Tank Problem
Hi all;
I want to share and also ask about something that happened this evening. As I started checking all my fuel lines, preparing for my first fill up of the fuel tank for engine testing for the 1st time, with difficulty I was able to see some sort of a brown shush or corrosion at the bottom of the Plastic tank, I was suspicious and took the tank out.
All lines below for draining the tank, were cracking, full of crap inside (with part of that brown shushy and oily thing I saw at the bottom of the tank. I'm not sure what this is, all the fittings inside the tank are completely corroded (light blueish powder on them!). If I would have gone with the testing or taxiing, my lines would have been all clogged and the engine would have stopped. I'm happy to have done this inspection. I bought this plane 70-75% complete and I've continued with the project. Probably the previous owner left some water there that provoked this corrosion inside.
So, is it possible to clean that stuff with a particular product? I currently left some gasoline inside to get that stuff diluted. Im going to change all the fittings. even the fuel probe might not work anymore.
Does Titan have all the necessary fittings for this fuel tank in a kit form? I think I'll have to take off the 2 draining fittings at the bottom as well, what compound should I use to seal everything back with new fittings? Do you guys use a urethane hose inside the tank?
Your ideas are appreciated! thanks,
Rob.
