to bad that fan is $9.95 a piece and the delta is $20+ fans are not something I like to spend loads of money on
no idea on the tubing itself as i use feser tubing.. but it is the proper dimensions
I assume by the time i edit this message there will be 8 more posts.. god you guys type to fast..
with that tubing you need to look for 1/2" ID x 3/4"OD compression fittings will list the size in a system like that
