Oil leak in Vacuum hose...

I seem to have an oil leak in one of the hoses coming from my vacuum pump.
I started the van up yesterday and oil just came squirting out.
I am not a super-do-it yourselfer but it looks like I can just unbolt this hose and reattach a new one. I am assuming that draining oil would be involved in this.
That I would be comfortable with.
I deal with CVI in Richmond and live in Maple Ridge so I think the towing cost would be extreme.
Does anyone know the part number for this hose?
I have attached a picture to make sure I am correct about the vacuum pump part.

dont know the part number, but you might be able to get one used from one of the dealers. be sure though that its that house and not something above it like the turbo.
its not a hard hose to swap, go ahead and change your oil at the same time, since youll be draining it. or you could just drain from the hose into a container. if the engine is cold, most of the oil will be down in the oil pan anyway.
wear gloves and have plenty of rags handy, and maybe even put down some cardboard in case it get a little messy

Not a lot of oil will come out when you remove it, just take it off and go to an industrial/hydraulic hose place and see if they will make one up, they are often quite helpful.

that is the oil feed line from the engine block
it's a female to female hose with a banjo bolt on either end.
If you remove it and take it into Lordco or Canadian Tire, they should be able to match it up as it is not a high pressure line.
Failing that, pickup a new/used one from one of the JDM guys.
Take Ari's recommendation to look for an oil leak from above either at the turbo or at the opposite end of the hose at the block.
Hard to tell from the picture but it looks like there is a hairline split when the hose is crimped which would require a replacement.

We have the oil feed line for alternator, you can contact me if you need one.

Must be something the time change or temp. change brought on as mine just started leaking as well. If someone has actually done this hose swap could you enlighten me on how you accessed the upper bolt as I haven't been able to get any of my 17mm wrenches to grab it even though I did my best impression of a contortionist.

No joy in attacking from the front, kept running into engine protrusion. Finally got it after majorly stubbying a combination wrench, removing oil filter and then it let go. Putting the top bolt in was a different matter all together. Got to be a contortionist to work on this thing.
