My kit arrived in 1996 and included was Neoprene hose, Aircraft spruce part number 05-00400.   

            

        I unpacked this yesterday and the hose has gone completely brittle and shatters very easily, I suggest that you check if you have used it anywhere.   

            

        Keep well

As far as I remember I found no use of it apart from filling it with water and using it to make the fuselage level while building.

 

What was it actually meant for?  Pitot&Static from probe to instruments?  I made those mainly with alu tubing.

The 3/8 I.D. Neoprene hose included in KIS kits was intended for the fuel line connection between the fuel tanks, and the fuselage. The manual is a little vague, but there is a drawing of a typical aircraft fuel system included in the TR-1 Builders Manual (Airframe Assembly section page 8 ). I did not check, but I am sure the same drawing is in the TR-4 Builders Manual. The drawing comes from our faster, sleeker, and much more difficult to build cousin, the Lancair 235/320. 



The black rubber hose is a very important piece to the KIS aircraft. I can think of 2 real important reasons for this hose. First it makes hooking up the fuel tanks – simple. It would be a lot harder to install a metal piece of tubing in this tight spot. Second when a wing panel breaks off in a crash, the neoprene fuel line would separate very easily - you won’t have to worry about the fuel line whiplashing about the cockpit (hopefully you all have plenty of Adell clamps or the like securing the fuel line inside the cockpit).



Vinyl tubing was also included in KIS kits for use in the pitot static system. Some items included in the kits in fact have a shelf life, and that includes the neoprene, and vinyl tubing (tires, unused resin and adhesives). KIS kits are now reaching the 25 year old mark, and owners that have KIS aircraft built with these original materials need to seriously think about replacing or upgrading them if they have not done so already. The vinyl tubing in my 23 year old is still somewhat serviceable, but I am upgrading to Nyloseal tubing, and fittings - those will last a few lifetimes. 



Some builders did not follow the Builders Manual, it’s just the nature of homebuilt airplanes. Some installed that black rubber hose from the fuel tanks all the way through the cockpit to the firewall (a very bad idea). My TR-1 had that black hose from the tanks through the side of the fuselage, then slid onto the aluminum tubing (no barb) held on by 2 hose clamps, running 45+ psi automotive fuel pumps in each wing slosh tank. The return came from the firewall fitting into vinyl tubing, to the fuel valve, back into vinyl tubing to the tanks. That tubing is now petrified. What’s in your fuel system?

My TR-4 has the neoprene hose from the wing to the fuselage as per the plans. One of them started leaking (old age cracking) after 9 years of use. The hose is very inexpensive so I now have it in my "scheduled maintenance" to replace the hose very 5years.

Fuel system problems are about 25% of the mechanical failures leading to accidents in homebuilts.   I would switch to real aircraft hoses (like aeroquip 303) and hardware for any aircraft system.   It is not hard to make up the hoses yourself if you get the mandrel tool.
