replacing the vacuum lines

Think im going to replace all of these as i keep hearing people loosing boost because of tired old ones that are cracking. i still only want black hoses, not much of a fan of blue or red. what diameters will i need to order and wheres the best place?

thanks in advance

i would also like to know this info,cheers

sizes needed were

4mm- 2 meters

5mm- 1 meter

6mm- 1 meter

I think most will be about 4mm ID and there are plenty of shopes on ebay that sell the silicone tubing and in black too. I used 3mm ID and were quite tight in places.

cool i wanted this to but am goin for blue ones any idears where to get them from thanks

hello, cheers for the advise, but whats with the dont use silicone hose on this forum then, how much do you think it would be to buy all hoses from toyota,. my car is a 94jdmTT,has 79,000-80,000 miles on it, generally the pipes seem ok but some are like china in that i know if i grab ahold of them they will crack into, also sure i have the 2nd turbo not coming in all the time, because sometimes it really goes and other times its just not right, i can feel there no 2nd tubbie, me thinks hose split somewhere

dont rule out faulty vsv's as the cause of your 2nd turbo not coming in

yeah ive been reading alot about them vsvs, one down the side by turbos seem a right pig to get at. did find one hose around the rear of the engine by the firewall just a few hours ago where one of the steel clips was sticking into it, got me plyers out and moved the clip away from the hose, theres a nice little cut in that hose now fromthe clip digging in to it, but dont think its gone all the way thru.

...but whats with the dont use silicone hose on this forum then...

Most silicon hose is not reinforced like the stock hoses. I think they are more prone to splitting and popping off IIRC.

You can get silicon hoses with a reinforced lining but you will pay more for it. I havent a clue how cheap/expensive OEM ones are from Toyota - but Steve Manley (do a search) may do them cheaper than most other dealers.

As mentioned, don't bother with low grade silicon hose. Use the high quality reinforced lines. The strange thing is it's actually cheaper than the 'bling' coloured cr*p! and certainly cheaper than Toyota.

Which pipes did you buy from here? How much of each size do I need thanks.

See post #3 in this thread regarding sizes/lengths: http://www.fuelsystem.co.uk/Hose%20Connections.pdf

Has anyone priced up a full engine vac, pressure and breather hose kit from someone like Nic? I would say a complete set of new stock hoses for the TT and breather system would make a good Christmas present for a lot of people

When I had my boost problem on my second turbo recently, I replaced the split pipe with a 4mm reinforced fuel line pipe. Its really cheap, and can withstand up to 14bar, so easily up to the job. It looks good in black too.

See post #3 in this thread regarding sizes/lengths: http://www.fuelsystem.co.uk/Hose%20Connections.pdf

The vacuum hoses only go up to a maximum diameter of 4.5mm, the sizes quoted above go up to 6mm. So which pipes do I need to get as I want to get it right first time. Thanks

Can confirm that these diameter and lengths are correct? If they are I can supply HKS or GReddy hoses in these sizes.

4mm- 2 meters

5mm- 1 meter

6mm- 1 meter

Hmmm what sort of price would we be looking at Nic? PM if you want

Bumping an old thread.

I am going to tidy up my engine room and the vacuum hoses that are there now are shitty quality so where going to change as many possible without removing any larger parts.

Does anyone know about how much I'll be needing to change the visible ones? If I remember correctly it'll be mostly 4mm?

Cheers

4mm & 6mm i used.

just order plenty of it, from ebay, better have too much than too little.

nice thread resurection btw

does anyone know the best place to buy high quality 4/5/6 mm reinforced vac lines from? in black

Wurth.

That's fine, too. Gates is good gear! Anything's better than plain silicone though.

cheers for that. think this is the stuff il get then as the sizes on the wurth site were a little off. this gates stuff is 4/5/6mm cheap ish too. just waiting on an closeup photo of the gates pipework now, just to make sure of what it looks like, what to stay as close to oem look as possible.

It looks just like stock. I use it when the Wurth rep has disappeared.
