How soon do you need them? I would trade for the ZZPs if you wanted to ship them ahead of time so I can make sure I get the L32s to the right length/ height.
Keep in mind, I don't have access to a TIG welder, and due to that, the lines I would probably be using rubber fuel lines covered in a thermal coating instead of braided steel lines like your ZZPs have. I would keep the length within NHRA specifications and ensure that they seal without leaking prior to sending them out, as long as I still have my 04 upon completion.
I could also add a fuel pressure gauge if you provided one. If this set works out well, I would consider producing them for others, since I know how hard it is to find returnless rails that fit over a full size IC and a Gen V.
