FUEL LINE Y 1/4 INCH

This is a Y-shaped fuel line fitting, 1/4 inch, used where a single fuel feed needs to split into two lines - the typical setup on a twin with dual carburetors running off one tank outlet or petcock. It's a simple, low-cost piece of plumbing but it's the kind of thing that cracks or goes brittle with age and starts weeping fuel at the joints without anybody noticing right away.
