Upper Wing Fuel Tank questions

[Jerry]

I'm close to putting all the pieces together for the upper wing fuel tank.

Questions:
- It has two drains (one left-back, one right-back) in the tank. Is this standard ? What do others have in their upper wing tanks ?
- It has two outlets (basically in the same locations as the drains) in the tank. Is this standard ? And... what do other have in their upper wing tanks ?

I'd like to keep it to one drain and one outlet.

thanks
Jerry
