Although it may seem odd at 1st that MikesXS sells his fuel line in 11.5" lengths, he does that for a reason. Cut one in half and it provides 2 lines of the exact length needed for the older 2 petcock tanks.
Many people seem to think additional fuel filters are needed. That's simply not true. There are usually 2 provided by the factory, one on top of the petcock and another screen over the float needle seat. I've never added additional filters to any of my bikes over the last 40+ years and never had any problems. On the other hand, I read about fuel delivery problems all the time on lists like this from people who have added filters. I've personally worked on many bikes over the years that had issues because of added filters. Bottom line - clean your tank and don't add extra filters. They're more trouble than they're worth usually.
