Whatever I have on the shelf when I need to make one. I have a mixture of Aeroquip, Jegs, Fragola, and some Summit hose ends. Usually use the Jegs or Summit house brand stainless braided hose...the normal stuff, not PTFE. Never had an issue w/ any of my lines on the oil side. Fuel lines I've had to replace a couple once they get over 10 years old and develop pinholes.
