904 cooler lines

[Canuck Bryan]

What size of tubing should I be using for my transmission lines? I don't have the originals to measure and want to make sure I don't go too small.

Any pictures of plumbed in lines would also be great.

Thanks,
Bryan.

5/16. 3/8 if you want beef.

i did 3/8 steel tubing wrapped in asphalt poly-loom on my setup, mainly to avoid pinholes from being rubbed into the line over time, and the drivers side head pipe is pretty close as well. did two 90 degree brass adapters out of the trans, hugging the bellhousing super tight, up between the starter and the block, along the oil pan/block rail, and ending right off the front drivers corner of the pan, then 3/8 flexible line from there to the aux cooler in front of the rad.
