Kimberly,
A very nice solution.
What do you use for gasket material? The black one between the plate
and the tank?
Have you had any problem sealing the filler hose to the tank? Do you
use any sealer, or just the hose clamp?
Since the hose is on the outside of the tank, gravity causes the fuel
to leak outside that joint.
Thanks,
Hugh

>> 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,
>>
