Question about expansion tanks??? My radiator is mounted lower than i was wanting to, and know ive been told i will need a expansion tank to fill it, and to release any air inside the cooling system. Im running -16 to and from my motor to my radiator. Question is how exactly do i route the lines for the expansion tank, and what tank would work exactly. Here is my build thread, it has pictures of the setup. Thanks

I built my own expansion tank. Need a setup that doesn't have a cap on the radiator (I think). I used some spare 4" aluminum tubing to build a tank. welded a -10 on the bottom of the expansion tank and on top of one of the end tanks of the radiator. I then ran a -10 from the tank to the radiator. On the vent lines coming from the crossover tubes on the heads, I ran a -4 line from those back to the side of the expansion tank.
my tank:

The radiator setup I have sitting here is the same deal that Brian built. Small radiator with -an lines to and from the motor, pump is on the radiator itself. There's a -8 line that will run from the radiator to the expeansion tank, one line off that under the cap that will run to the overflow bottle, and a port on the expansion tank to let the steam lines from the engine run back to as well. Should work out good.
I got my expansion tank form Mezlere. It has a cap, AN 8 at the bottom that I ran to the inlet of the pump and AN 4 about 2/3 up the side that I ran to heads vent crossover line, and over fill to a overfill tank.
Works great!

Awesome guys, thanks. I was having a hell of a timing searching for this ****. My radiator does have a cap on it, can i just put a cap on it, or will i need to tig the hole shut? Thanks again!

How about if i tig up the radiator cap, and run the -8 to the former cap location. Would that work good? Wial im welding up ****, should i remove the overflow hose barb piece as well? Just make it have the in/out for the pump. So that way everything else in on the expansion tank.
