My Vanagon, 85 1.9l Automatic California, has a small diameter hose
running from the fuel tank, meeting a plastic adapter which connects
to a larger diameter fuel hose which runs to the fuel pump.

This plastic piece has cracked and started leaking gas.    I called a
VW parts counter and they couldn't figure it what I was talking about.

Does anyone know the part #?  Or perhaps where to find a replacement
part that is metal?
