what pipes are 5/16?

Hello,
What pipes on a 1986 K5 Blazer are 5/16? I bought 25FT off from summit to replace a broken tranny cooler line. I might end up replacing the second one for the hell of it.
Thanks
Adam

tranny and some gas lines..

The tranny cooler lines are usually 5/16" tubing,so is most gas line on 6 cylinder and small V8's--350's and larger use 3/8 line(some smaller engines do too--no ryme or reason!)...thats about it--brake lines are 3/16" and 1/4"...25' of 5/16 ought to last you quite a while,unless your tranny lines rot out as fast as mine do here...
