Bryan,

Having the stock system myself, I've had no = failure of any=20 kind in 860 hours to indicate a need to run other than fuel from wing, = to=20 header, to engine. Additionally, I have a filter in the line from = the=20 wings to the header. For me this is a convenient filtering=20 technique.

I may be over simplifying your T commentary but = many an=20 aircraft has left the sky to only find fuel migrating into tanks where = we=20 thought it shouldn't. Take the Voyager for instance. Check = valves=20 may be an additional item needed to make your system run in both ways = (to header=20 or to engine).

>but they would feed at = the same=20 time equally< This is simply a = hope. In reality, your rudder ball centering skills will determine = from=20 where the fuel comes.

For=20 the 320, the 1/4" lines would probably be sufficient. I draw over = 20 gph=20 occasionally when racing. I like my 3/8" line from the header to = the=20 engine.

Subject: 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 = header.=20 Then a 3/8" line feeds my engine. In this configuration I = can only=20 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 I=20 don't want to re-plumb the wings with 3/8" lines. Can I connect = the 1/4"=20 wing tank lines into a "T" with a 3/8" exit and run the line to the = selector=20 valve? Essentially the wings would not be able to be selected but = they=20 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
