I have just installed a Quick UK header tank on my Rappy 30. I noticed that the muffler feed and fuel feed lines were the same length when i took them off. I have kept the length of the feed between the main tank and the header and the header and the carb as short as possible (as per Rays manual advice), and cut new line muffler the same length. Theres alot of muffler line, especially after installing a filter. I was wondering if its critical for the muffler line to be the same length as the fuel feed line (pre and post header tank being the total length) of if I can just trim it down to tidy it up.
Cheers for any help
