If t'were me, I'd use the ID of the non-return valve as a guide, as that's the bottleneck in the system.
Beat me to it - buy yourself a non-return valve. I use 1/2" pipe, but 1/2" pipe isn't necessarily 1/2" dia. Depending on the make and type it could be quite a bit smaller. I use high pressure oil line - same thing as vacuum as it has steel mesh inside. Try your local hydraulic supplier.
http://www.ebay.co.uk/itm/MG-Triump...arts_Vehicles_CarParts_SM&hash=item4177d13698 What do you reckon gurus? taper thread, 10mm ID hose....could run straight from the manifold up to the servo with a ste down reducer at the servo end.....???
no, apparently not....do you happen to know the approximate route for the metal pipe? Does it run along the nearside or off side? I was thinking of flexi hose thru the 3 & 4 cylinder side rear, crossing over in solid pipe at the rear x member and a straightish run up the offside chassis rail to the servo....not really had a proper look yet
Starts at 3/4 as you say then depaneds on whether LHD or RHD. There should be a solid piece spanning the sliding door, but not always. If not, pick a neat route and go flexi all the way.
Thanks Zed....maybe sounds like I'm making a mountain out of a molehill with this....main issue has been all the different 'standard' measurements quoted by retailers (as much as anything) I've done enough bodging in my time to know that imperial and metric hoses can vary significantly....think I'll probably use good quality flexi hydraulic pipe....less connections to leak, plus i can route it wherever (within reason)
Remember it sucks so tends to make the seal rather than break it. Your hydraulic supplier should have a barbed comnnector too. Mine's as cheap as chips.
it's not good for my over-analytical mind browsing these hose and fittings suppliers looked into using copper but the price has rocketed
I pay about £20-30 for the manifold fitting, 6m of pipe and a handful of stainless clips. You'd do well to do it cheaper.
the stock metal tube is about £30 delivered,...found some good hose which works out about £7 a metre, so may go metal with shorter hoses...
