I found McMaster Carr to be the cheapest source for 3/8" stainless line. I bought a roll of it and some backup sleeves and tube nuts for 37 degree flare. I will use it for all the fuel lines on my truck, about 8 total. I bought some Aeroquip -8 braided stainless hose assembly's with the Teflon inside to allow for some flex between my engine and frame.
I should have pictures in a few weeks.
