I parallel the top of the oil pan... that will
put you over the K-member.. but I run hard line..
if this is a 904 or 727 its 5/16 tubing.. a 518
type uses 3/8 tubing... also if running headers
the lines can get close to the headers so I run
a thermo barrier that slides over the tubing...
its good for over 1000*.. works fine on my Rampage..
keep it tight to the pan
