One of those is thin enough to fit in the LE wing?

Yeah, I used their stuff for the filler necks of the fuel and oil tanks and bought a 6" diameter X 12 piece to make the oil tank. The end caps were too heavy, though, so I made the caps out of 1/16". Good stuff.

My Al Pro-Seal fuel tank is coming together nicely.  I now need some guidance from the collective wisdom of the group: the dimensions of my tank are 7"D X 12: W X 14" L.             
1. With such a short L do I really need both a front and a rear fuel outlet?
2. Assume one outlet.  Front or rear? Why?  My thinking is if I'm up in the air and low on gas I'm looking for a place to land and probably heading down hill. Ergo front placement. If I take off with so little fuel that I'll uncover the front outlet, I deserve whatever I get... So what do ya'll think?  Thanks for your input with this.  DA

Why not put in a front outlet during construction and plug it with an NPT plug? If you find that you need it later, just screw in another petcock. That is what I did on my FG tank.

Kam, tks for your reply. I never thought of that. even though I  have the necessary HW for two outlets. I've had four planes: 7AC Champ, RV-4, Citabria, and a Ridgerunner. I never much paid attention to where the fuel outlets were. I'm pretty sure the ridgerunner had one outlet in the rear. Chuck from INdiana has broad experience with multiple planes.  Hopefully he'll comment.

Mine is the same shape of Kam's, and I have an outlet front and back joined at a shutoff valve. Quick drain at the rear inboard. I think (memory fails me, I'm old) I documented it all in the build thread.
