Now I'm thoroughly confused!

The drawing on Wilfy's Van-Again page seems to match most closely what I
have but when I look up the part number it says it's for a 2.1 L engine.
Hmmm... Always thought mine was a 1.9 L.  The part number is (I think) 251
265 056B.  It's a short hose approx 5/8 in inside diameter that runs from a
"T" fitting under the vehicle then flares to approx 1 inch inside diameter
where it attaches to the front of the passenger side head.

My VIN once again is WV2XB0256FH077873.

Can someone help me out on this one please?
