RE: fuel tank fitting
Jef,
It probably doesn't matter for your application, but I think you've got them in backwards from what they were designed. The short side goes in the tank and the long side goes outside. Its OK if you use the plug that has flat plates on the outside, but if you use a plug that has a cap, then the cap will bottom out on the neck before the rubber plug is compressed.

RE: fuel tank fitting
Bob,
I see your point , I checked the fittings with an alumininum cap and it looked fine.
I used the hardware that came with the tanks and it works fine too. Tanks are ready to go in my L-39.

RE: fuel tank fitting
They work great, don't they! 
Whether or not the cap fits on it that way might depend on the thickness of the "lip" on yor rubber stopper. The ones you have look like the ones from my F-4 in that the lip is quite thick and would hold the cap away from the back of the neck. The duBro rubber stoppers have a thinner lip and the cap might bottom out on the neck before the lip gets sufficiently squeezed. Of course, it will work either way with the flat metal plates...
Thanks again Rich! Now, who's going to market them for the next time we need them?

RE: fuel tank fitting
Rich, These things are great. Here is a photo of them installed in Eric Clapps new Saber tanks. We will do a build thread on this Plane in the next few days. Its a Skymaster F-86.

I will be starting my build thread on the FB Rafale after Christmas

RE: fuel tank fitting
Here are my Rafale tanks completed, I like to use 3/16" (4.75mm) tubing for my fill and vent lines (interconnection lines) and I use the stock 5/32" (4mm) tubing for the line to the UAT.
The larger lines allow for a faster fill up.
In order to get the larger lines thought the stock rubber stoppers I first insert the 5/32" tubing as a guide, then slide the 3/16" tubing over the 5/32" tubing.
Works quite well.
Of course you have to drill the metal parts out to accept the larger tubing.
The larger tubing also makes for a tighter fit of the rubber stopper in the Aluminum tank fitting, here is where a bit of dish soap works well with a bit of muscle.

RE: fuel tank fitting
I always use safety wire - double wrapped before twisting. If you use zip ties, you generally don't get even pressure all the way around the fuel line - especially where the "clasp" on the zip tie is. In the worst case this can lead to a leak, either fuel out or air in, in the line.
