Been a long time since I was around and it's been a long time since the 406 was out and about. Just sits in it's garage nice and clean now I've got a work car, can't bring myself to get rid

Anyway, on it's last run out I took it to a friend who did a bit of diag on it to see why it's never been 100%. We've come to the conclusion it's got a vac leak as all checks out alright. Problem being is I don't know what sizes the hoses are to order off the tinterwebby. I went to the stealers and unfortunately they have stopped making them and the guy couldn't tell me the sizes. I went to GSF and they looked blankly at me. My Haynes Manual doesn't do the 2.0L Tubby engine, so I'm at a loss.
Can anyone tell me what sizes I'm looking for and if anyone has a good place to get them from, I'd be very obliged.
Thanks in advance folks.
