Just broke the plastic "T" connector that branches from the 5/8" fuel hose off the filler tube. It basically disintegrated when removing a line. This is on a '74 standard beetle, fyi.
The piece is a ~16mm tube with a ~5mm intersection branching off to the vent hoses. Tried the local Napa, Autozone, and Checker, but cannot seem to locate a replacement. Anyone have a source? Maybe a brass plumbing fixture of some sort? (can't think of one that will step down that much)
