I am completely new to the AN-6 fittings and I am looking to run Nylon lines on my 41 buick. I have a Tuned Port SBC in it and I was looking to relocate the route of the fuel lines using AN-6 fittings. Every kit I fond has braided nylon hose with it, but I was looking to use the non braided lines I already have. Is this possible to do? DO the AN-6 fittings work both with/without the braided covering? This is the only thing holding my up from getting my car started here soon. Thanks in advance for any info. Im currently at work, but will try to respond as soon as possible.
