Bryan,
 
Flowing both wings to the engine=20 simultaniously in a low wing airplane is not a good idea. It is = unlikely=20 that they will burn equally and if one pickup sees air, that's what = will go=20 to the engine since it's the least resistance.
 
If you install an automatic header feed = system, you=20 can feed the header from both wings at the same time. The auto system = keeps the=20 header full, or almost full, as long as you have fuel in either wing. = The stock=20 LNC2 system, with the addition of an automatic header filling = system, is a=20 very safe, simple and dependable system. This gives you the = advantage of=20 flowing both wings together without the hazard of a direct = (both) wings to=20 engine hookup.

Subject: [LML] Fuel selector = Valve=20 question

I want to run this idea I have past the group.

My current set-up is 1/4" lines coming from my wing tanks to the = my=20 header.  Then a 3/8" line feeds my engine.  In this = configuration I=20 can only feed the engine from Header only. This is the stock Lancair = 320 fuel=20 system.

I would like to be able to run my engine off my wing tanks if = needed but=20 I don't want to re-plumb the wings with 3/8" lines.  Can I = connect the=20 1/4" wing tank lines into a "T" with a 3/8" exit and run the line to = the=20 selector valve?  Essentially the wings would not be able to be = selected=20 but they would feed at the same time equally. 
Would this idea work?  And if so what type of Andair valve = would I=20 need?  One with just a Left/Right/OFF  And I would have them = custom=20 engrave the bezel to read Wings/Header/OFF

Thanks
Bryan
