Hi Colyn,

 

We're working on the same challenge with our IV. Andair doesn't make (yet?) a 3 way duplex valve which is what would work best for both of us. I was thinking about using 2 seperate 3 way valves, one 1/2 for fuel and one 1/4 inch for return. Either way, I think that we'll be stuck with 2 valves.

I have a IVP with the usual left/right/off , supply + return,  fuel valve.

 

I have a third tank to plumb in.

My thought was to put a second valve on the way to the right tank.

This would be exactly the same kind of valve and would select between right (wing) tank and

aux (baggage area) tank.

 

So it would look like this:

 

               engine

                 ^

                 |

                 |

                 |

left wing -> main valve <--2nd valve--<- right wing

                              ^

                              |

                          aux tank

 

So this is full retun on all tanks and I should be able to

run directly from any tank.

 

Can anyone think of a reason why this valve arrangement would

not work reliably?
