Thanks Mikki, good advice I will keep laundry powder well away from the car
Yes on my car the delivery pipe is one piece. Looks like its well protected (crimp joints covered by thick foam rubber) and already painted.
Only the return hose has the crimp joints exposed.
I found this not-so-good site which has some D2 manuals on it. Seems that the banjos on the pump are both 50nm so need to be quite tight. I couldn't find settings for the ones on the rack end but I will assume 50Nm also as one of them is high pressure.
The high pressure hose bolt on the pump is a real pain, the hose fr the reservoir is in the way. I'll have to loosen it and move that hose to get to the bolt.

Its funny how when doing something else you find unrelated things. I think I found my gearbox oil leak. The hoses/pipes look good and dry all the way to the radiator. But on the gearbox one of the banjo bolts appears to be missing a washer, and that pipe and bolt are covered in oil. So that's my next job, to replace that bolt or at least the washers. At least it looks like I dont need the out of production hoses! for now...
