Subject: Coolant header tank & Coolant filler neck thingy???

Hi Guys;
I've been away at tech school for a few months and am just beginning to get
back to work on my engine. I did fly home every weekend, but just worked on
painting the plane so this is the first I've worked on the engine since
doing coolant flow tests back in December.
In an effort to design the most efficient coolant system possible, I've
built my own header tank. I've drawn a diagram of the system similar to the
diagram provided by Lyn. To finish this tank I need to put a cap on it. I
searched the internet for aluminum filler necks and found some in England,
but while looking through my repair manual I found a pic of a bolt-on
plastic flange mount filler neck. This is shown in the pic "rad cap filler
neck". Can somebody out there tell me if this is just a mount for a filler
cap or if it is for a pressure cap? Can I also get the dimensions of it with
& without the cap.
The "coolantheadertank" pics show how it will be mounted & the "coolant
recovery bottle" pic is an old snowmobile coolant tank modified. Side port
on this tank has been plugged and bottom port has been modified to accept a
3/8 hose.
Comments, criticism are welcome, but I'd really like the info on the filler
neck thingy, so I can order one tomorrow if it is appropriate.
Thanks
