I think I am going to take out the AN line and replace it with steel or aluminum and then use true vapors guard on the connecting pieces. I’ll used AN fittings to tie it all together.
I didn't even see your original post about it all being the AN line. I assume that is the steel braided but with a rubber jacket? You can get PTFE lined hose from many places (I got mine from https://hotrodfuelhose.com/) and that would definitely make a massive difference. Hard line is also good, but if you already have the clamps in place and don't want to bend new lines, a PTFE-lined hose may be a good option. Unfortunately each PTFE hose takes specific hose ends, so you won't be able to re-use any.
Finally got around to making the lines. PTFE lines worked great. No more gas fumes! They are a pain to work with but well worth it.
