Ahh, you guys are great! Thanks for the warm welcome!
The LooseNut name comes from a little joke, something along the lines of ... "I think the only problem with this plane is the loose nut holding the control stick ..."
Don't be giving me too much credit ... I only have one tank finished! And, by the way, it hasn't been leak tested yet ... so maybe not?? Anyway, it looks to me like it'll hold the gas inside ... and I'll get to the leak test "real soon now".
So, I put the first tank together using the instructions from Vans. It works ok that way, but, I sure spent a lot of time cleaning stuff!
Now recently I've read about this new technique of sealing in all the ribs, clecoing it, then waiting until the next day before riveting. Boy, this really makes sense to me now. I'll be giving that a try for the second tank.
By the way, I too had the briliant I-DEE-ER
that putting a return line (aka purge line) into the tank might be easier now than later. Kinda funny, my budget says carburator, but those fuel-injection gizzmos are pretty sexy! So I put in a 1/4" (-4) fitting into the root rib wth just a short straight tube into the second bay. I put a cap on it for now.
I picked a 1/4" return line for no better reason than ...
1))) When I looked at Van's catalog and saw the double Andair valve, it had 3/8" fittings for the the supply side and 1/4" fittings for the return side.
2))) Then I saw Airflow Performance's purge valve and that seemed to use a 1/4" line too (although I can't seem to find that now to verify).
Then I looked at Eggenfellner's Subies, and I saw they recomended using a 5/16" (-5) tubing ... dang, that's a wierd size!
So now I'm wondering how smart my modification really was. If I was going through the trouble, maybe I should have put in a 3/8" line and put it all the way out to the end of the tank where it can vent above the level of the fuel? I'm always second guessing myself!
I saw that ECI sells a fuel injection system (TITAN EXP Fuel Injection System) so, I thought I might ask these engine dudes what they recomend for the return line. I sent them a note asking this weighty question ... I'll pass on the answer when I gets it.
... I'll have to figure that picture posting thing ... and get a snap shot or two in here ... I sure enjoy the pictures of the work you folks have been posting up!

It's been quite a while since I checked in. My attention has been in other directions for a while ... I guess I'm too easily distracted ...
