Stainless fuel line for a 68 swb with blazer tank

[elf w/capital T]

I understand I can use the stock line from front to rear (rear of cab) line and run a rubber hose or make my own...

But..

I am curious if I could buy a replacement line for a blazer and install it in my 68 2wd swb...?

If anyone has anything good or bad to comment, I'm all ears. I don't want (my current setup) stock line to a 5 ft rubber hose... I want all steel and making my own is kind of the last resort.... and also what size should it be? 5/16 or 3/8?


Thanks!
