Service manuals with zero reference to changing out corroded fuel lines.
This is on my Honda VFR motorcycle.
I have two service manuals....one by Haynes, the other by Clymer. Neither one mentions AT ALL anything about fuel line replacement. Even though....this is one of the most common repairs made to ANY vintage motorcycle (or any vehicle for that matter).
Of course, I can figure it out on my own. But with all the crap in those manuals that I will never need......you would think.......
