240z/260z brake servo to manifold rubber hose

Hi there,

Looking for the rubber version not the braided one, both pipes either side of the valve please.

Prefer new or very good condition.

Have paypal, new to this forum but regular on Hybridz.org (24OZ)

Many thanks.

George

hi George, I just use a thick wall rubber hose, I run a L28et in my 280zx and have had no issues over the last few years

The moulded hoses are only available for LHD S30's atm.

Maybe RHD hoses will become available in the not to distant future...

You can buy just straight vacuum hose that will do the job, but I sense you are after the OEM moulded type?

I just bought normal straight vacuum hose today for this. I'm going to have a go at bending a wire inside the hose to keep it's shape. I'll let you know how it goes.

I noticed that Goodyear Rep says they can do moulded lines on their website, I'm not sure if this is a viable option though for one off's or small orders though.

Definitely interested if anyone comes up with other ideas.

Enzed stock this type of thing. It's a spring sleeve that goes over your straight rubber hose, then just bend it to required shape with no kinks.

Thanks for the input guys.

I'm looking for the moulded OEM look, I've seen those spring type things that go on the outside  but they stand out too much for me. If I can't source one, I will try inserting a copper pipe and bending it to shape.

Sensual sushi please let me know how you get along.

OK so I just used some wire I had lying around which is too big to actually use but it seems to work pretty well! I reckon if I can halve the diameter of the wire that would do the trick. Can anyone see any issue with having a wire internal to this vacuum hose (I would obviosuly trim it to be shorter than the rubber hose)? It should stay in place due to the kinks etc.

Here is the clean hose next to the original

And the braided sleeve hose next to the original. Does anyone know where you can by straight braided vacuum hose instead of using a sleeve like this?

I would just need to cut and heatshrink the ends to keep it together then get some new hose clamps and good to go 

here you go sushi... just find one with the right I.D

Do Nissan do them? Might be worth a try, they are normally pretty good.

Does anyone know how hoses are bent. My suspicion is that they use rubber that is only half vulcanised (not available to the public) clamp it in a mold and cook it which completes the process and sets the shape.

Last night I finally made up the hose. It loks alright, a few little modifications and I think it will be fine.

Benny I think those hoses on eBay aren't specifically vacuum hose. They would work for a while but then they weaken and the hose would just collapse meaning no or little brake booster 

This is the hose you can use to replicate the braided Vac booster hose:

Just cut the end off with the bend in it, insert a straightened coat hanger into the line & bend to shape

Ahh cool, thanks Lurchos, although it is not "Vacuum" hose either?

or this?

That looks like it will do the trick  I was hoping you could just by it by the meter in Aus but I guess not :S

not braided, but should work with the coathanger trick?

i measured my one to be 10mm ID, but the hose is in pretty bad shape, so it could have shrunk or expanded. what does everyone else have?

Depends how much you want to pay

I bought a set of these when our dollar was very close to the USD

One of them is listed as a reproduction part...maybe there will be more around in the future

hmm, not that much. i saw mckay have 8.8 mm plain vacuum hose, just not sure if its the right size

8.8mm is the direct conversion from 11/32", so you have the right type of hose at least.

Stock auto vacuum servo hoses use */12" size ranges, due to their thicker walls (when compared to pressure/fuel hose walls)

Considering their cost, it's a pity many of the Mackay hoses don't have an inbuilt check valve
