Oil pan/pump/part question

[vwtopia]

I am putting an 85 Golf Diesel engine in my 82 Diesel Vanagon. I finally got the engine installed today. I was waiting to install the vanagon oil pump and pan after I got the engine in since the Golf pan was smaller and easier to slide it under the van. I took the pan off to replace the oil pump and there is another metal tube coming out of the case into the pan. I looked in my Haynes manual but couldn't find anything about it. I had to bend it very slightly so I could install the vanagon oil pump. My old engine did not have that. Can someone tell me what the metal tube is for? Do I need to do anything with it since the oil pan will now be the vanagon type and not the golf type?
Any and all responses are appreciated,
Kevin

Dip stick tube?

I didn't think of that but I bet you are correct. I will double check that when I get home tonight. Thanks
