Hey gang,  It's time to begin the design of the fuel system.  I have little experience but I have placed a design document at this location:

http://home.comcast.net/~rlendon/Fuel_System_design_document_for_Zodiac_XL.doc



and would like feedback.  If I am off base here, let me know.



Basically I'm following the prints but substituting Stainless Braided line and fittings from Earls.  The document is linear in that it starts at the tank and ends at the line to the carb.

A few comments:



- since you are going with the Corvair I presume you will be following

William's design.

- consider adding a fuel flow sender and gauge. Fuel exhaustion is an all to

common cause of accidents and fuel flow can provide an instantaneous check

on the health of your fuel system and also help you track your fuel more

accurately.

- I'm paranoid enough about vapor-lock that I went with the Andair

extensions so I can mount my valve on the floor and the knob on the center

console.

Craig,



I have allowed for the pressure gage but hadn't thought about the flow.   And yes it is a Corvair the WW way.  I have been waiting for him to publish the 601 book but have gotten to the point I need to move forward.



Got any pictures of the Andair Valve mounted?



Thanks for the ideas.

Mine is still mounted in its box. But I've attached pictures of somebody

else's installation. Unfortunately I've lost track of whose plane it is.

I am more or less at the same stage as you are - I was considering  

quick disconnects at each wing root - any thoughts on these?

David,

I have an XL with the dual stick option.  The outboard bearing brackets for the system have holes in them for fuel line support.  In these holes, I mounted a AN bulkhead fitting.  The inboard side is connected to the fuel selector with braided fuel line.  I installed a hose barb fitting on the outboard side.  When I attach my wings, I will route the ZAC-furnished rubber hose from the fuel tank, thru the side skin and to this hose barb.  In that location, the connection, with a clamp, will be real easy to make. That is about as close to a quick disconnect as I want to be.

That is from my web site.

I wasn't happy with the location up on the panel.  So I moved it low to keep 

a pressure head on the valve.  It works fine.



Cheers

Craig and others,



Added a Floscan 210B to the design just down from the second pump, filter will come after that.  It will connect right to the Dynon unit I plan to install.



I don't see the need for a quick disconnect at the wings, once they go on I hope to keep them on.  I am planing on using the Stainless Braided hose though and keeping all the pressure on the engine side of the firewall.  The braided hose is much less likely to rupture if the worse thing happens.



I am going to have to experiment with some clear line to decide about mounting the selector valve low.



Thanks for all the feedback, keep it coming,

Matt what did you use to paint the inside of the fuselage with.  It looks

great.

Thanks, I'll make a note.



BTW: Matt's site contains a link to a very good article on fuel systems that

I've read in the past:

I used Stewart Systems water based paint.  It takes a little getting used 

to.  But I really like it.  This stuff is very durable and very safe.  I 

tried it on the interior to get the feel of it.  I am glad I did.  If you 

order paint from them they will send you a video that shows how to do it. 

They are really great to work with.

Good luck and happy building
