NO LONGER NEEDED

I need a replacement hose. I would visit Pirtek, but before i do if i can help anyone clear this from their shelf please let me know!

Its the pipe from the PAS pump to the brake booster.
Part number 857 612 065 E
Many thanks!

I should have a spare one of these, I did have a few but sent Mike one a couple of weeks ago...

Hang on you need one for a UR, just had a look on 7-Zap and they're completely different to an S2 hose.

After some time spent poking around on this, I can advise as follows...

There are (at least) two set ups on the ur (MB and, I think, the RR, although the RR may use ONLY the new styles...)
(The older WR setup uses a different bomb for sure, i have no other comment!

First one is
old style pump, old hose, old bomb.

The second is
New style pump, new hose, new bomb.

The pumps have differently positioned exit holes for the hose, and the hose uses either copper washers (old style) or recessed rubber (new style).
It is possible to use a new style bomb with the old hose and pump, by using a smaller banjo bolt. I have done this and it is not leaking (so far).
But, ideally, you need to keep all three components either new style, or old style.

The new bomb seems to be same as for the S2, so i assume the pumps and hoses are also the same
