servo hose question

[Wedgiebaby]

Apologies if this is a daft question, but I ordered a servo hose from JK. There is a bit of clear pipe on there at the mo, which was put on purely as a temporary measure to replace the original rotten one that was split and full of holes. Hubby went to put the new hose on today and it's much chunkier and thicker than the original and the temp one. There's not a big enough gap under the metal connector pipe and the new hose won't push on fully. The original hose was held in place with a jubilee clip, but there's no way one will fit on this pipe due to there being no gap. He's even shaved a tiny piece off the outside of the hose to try to get it to push on better, but it is still too thick. see pics....
Is there meant to be a jubilee clip on this hose? Any suggestions please?
Thanks!

Of course this isn't 'genuine Volkswagen OEM' vacuum pipe, just something that fits the bill (or doesn't in this case). The original hose was reinforced with metal braiding to prevent it collapsing. The sucking action also has the added bonus in that the hose with never come off because it is pulling rather than pushing.
It should have pipe clips but if the connections are 'that tight' it really won't be a problem without. If you have a piece of 2.5mm twin & earth (house hold mains wire with single copper core) you can use it as lock wire around the hose (two times around and then twist till tight).

It should be...12mm ID 3.5mm wall thickness, the original stuff is still available from VW at £26/m part No N 020 390 1
that stuff is no good
Brickwerks sell the right stuff
or here's an alternative..http://www.auto-performance.co.uk/produ ... cts_id=592" onclick="window.open(this.href);return false;

Thanks for your input guys. I know it's definitely different from the original braided hose that came off the van, but it was meant to be a proper, more modern replacement that lasts ages. I will ring JK on Monday and ask them why they are selling this, as it clearly isn't any good.
Think we will leave the temporary one on for now and get some proper stuff asap.

When it comes to van parts I would leave a camping equipment shop alone and use a quality van parts supplier .

I wouldn't be quite so condemning....it is probably stamped with the appropriate standards markings but clearly the outside diameter wasn't taken into account when they chose to stock this product.
You are the user trying to fit the pipe, I'm not saying you are doing anything wrong but it is rubber and should have a fair degree of flexibility to compress and expand, I know I'm being a little unfair because I have no idea how hard you have tried to fit this but from pictures alone it does look like it should fit. Then pushing an open jubilee clip under the hose close to the manifold.

Just go tell me to take a running jump lol.

And just to add my thoughts on this. Although some were rather quick to condemn my quick Sunday repair of using reinforced washing machine hose, its been on there for an amazing FIVE years now, hasn't collapsed and did the job. Available in Chilli Red or Cool Blue lol.

As said, the original hose was reinforced with metal braid to maintain the shape but providing the walls are thick enough, I don't think you need to be too pedantic about originality providing it can handle some degree of heat. You may well find the temporary repair lasts a very long time. The replacement you have is incredibly thick though and was clearly meant for another job entirely.

If it were me I'd stick with the temp hose for now and find something more easy to work with.

The new hose came from Just Kampers, along with a few other parts I ordered at the time. It was on their website as a servo hose under the T25 parts section, so I trusted it to be a proper approved part that should fit properly. Here's the link for the part on the JK website & note the review (which wasn't us and I wish I had noticed before ordering!) http://www.justkampers.com/review/produ ... ategory/5/" onclick="window.open(this.href);return false;
The other half is a mechanical engineer who does precision engineering, so is pretty good at improvising and making things fit. However, try as he might, no way was this hose going on that nozzle
Its just much too thick and chunky to push on fully. Its because the narrow gap underneath the metal nozzle and on top of the manifold is not wide enough to enable this thicker hose to slide under and push on flush. The manifold nozzle is pointing very slightly downwards, which also doesn't help. He did try shaving a bit off the hose, but it's such a hard, thick material, that it would have been really difficult and time consuming to get a half decent rounded finish so the jubilee clip would go on. After much cursing and several cuppas, he chucked it in the bin and put the old temp bit back on. I've just emailed JK to tell them their hose will not fit, so will see what they have to say about it.
This temp pipe was just an odd bit that Neil (who fitted the power steering) had laying about. I will get a proper one sometime (have just googled and found a local VW parts supplier less than a mile away!) but In the meantime, we will leave the makeshift one on as it's doing the job and seems to be perfectly ok at the mo. You never know, maybe it might even last as long as washing machine pipe does!

Ask at your nearest VW commercial place. Good chance they can get it. Everyone seems to forget VW themselves.

true..
When I last asked it was still available.
I ended up fitting a used item but it was from a late van with the updated VW version.
It's a PTFE pipe with a short silicone connector.

Just Kampers, did you say? Mmmm...

Well, not everything they do is bad but clearly in this instance that hose hasn't been tried & tested. Well maybe tested, but never tried.

I should make it clear (and I did the last time this came up), despite the fact I used it on mine, washing machine hose is NOT suitable as servo vac hose unless its at least reinforced - most isn't and will flatten once it gets warm. I was just lucky with the stuff I found that day and I kept the rest of it should I ever need it again. I'm not sure how you can verify that but I guess if you can flatten it easily with a big pair of pliers, you might want to give it a miss.

You can ofcourse run a sleeve inside hose to help maintain its structural integrity. Have done that with water hoses sometimes.

Finally, you might be surprised/shocked at just how much cheaper parts from VW are sometimes, compared to those offered by the well-knowns. I just have an eye/feel for whats good or bad but then I was in the business many, many years. Also, a part made by one manufacturer deemed poor quality, can become better quality once the returns pile up at the factory. Likewise good parts can decend into carp just by one minor manufacturing change. For those not so clued up in terms of making quality judgements, then you go to a supplier you feel confident with, regardless of cost.

Thanks for all your comments guys.
I will try the local VW place I've just found near me. Didn't know it existed before. Hopefully they will have some, or will point me in the right direction if they don't.

I got my replacement reinforced servo vacuum pipe from a more modern Audi in the breakers yard. It was as good as new and was 99% the same as the original one I took off and only cost £2

It doesn't help if you don't get a full technical description for parts. The times I see things like tube 30mm diameter - you don't know if it is inside dia. or outside and no mention of wall thickness. These sellers don't get my custom as it is a pain having to ask. Buying local where you can see the goods is more preferable in a lot of cases.In fairness to JK they do say 2cm which may refer to OD.
