Custom-made hoses
I have to connect my x-flow water pump to my new inlet manifold. I can either use a length of straight hole in a big 'U-bend', or make a
connection using several right-angle bends, ali tube and lots of jubilee clips, or I can get Samco (or similar) to make up a custom hose.
The straight hose will be ugly, get in the way, and probably strain my manifold connection. The made-up connection will work OK, but won't be
pretty and is likely to be a potential source of leaks.
Obviously, the last option will be the neatest, and also the most expensive. The question is - how expensive?
Has anyone here had a hose made to measure and, if so, what sort of cost?
cheers,
David

There is a compnay in lincoln called Roose Motorsport who do the silicone hoses like the samco ones alot cheaper and the will make specials for you
cheap to.

I had a quick look - it ain't going to be cheap! When you see words like...
quote:
All our hoses are made by hand using our in house manufactured mandrels. These mandrels represent the inside of the hose. Our design and tooling
department manufacture tooling (mandrels) from top quality stainless steel and aluminium and then highly polished so as to give the inside of the hose
a smooth surface.
...you just KNOW that big money's involved!
As a guide, an off-the-shelf 90-degree bend, 19mm i/d hose with ends about 50mm long costs £9.01. The are cheaper than Samco, but 'cheap'
is relative...
All of a sudden, 2 bends and a bit of ali tube sounds very appealing...
UPDATE:
This place seems to be reasonably priced for stock off-the-shelf pieces. No idea of their reputation
or quality...

David,
What about using Ø15mm copper pipe and a pipe bender or one of those flexible corrugated lengths of copper pipe (Homebase) to make the shape you need.
Solder a straight coupler solder ring fitting on each end to provide a lip for the hose and jubilee clip to secure against. Then just use a short
length or rubber hose at each end to connect to the manifold and thermostat fittings.
Nice, neat, tidy and reliable solution. Copper pipe paints well too so will look good in the engine bay with coat of satin black paint.

I was considering copper pipe - I could always polish it up, like they used to do on vintage cars! 
I'm sure copper would work OK, as this particular bit of the water circuit is just a bypass until the thermostat opens - it's required,
but there's no requirement for high flow rates or anything like that.

I used these guys who made me up a full set of bespoke hoses for £130
Linky
Phoned them - Faxed through a sketch - Agreed a price and away we went
If you pay peanuts...
Mentale, yar? Yar, mentale!
Drive it like you stole it!

is it really that complicated?
The tube is about 20 mm O.D. - I have length of silicon hose, the big blue one in the big picture, no need for any connectors in between, just routed
in a big loop.
 
thermostat to radiator hose
If you do get custom hose made, which I cannot for a nanosecond imagine will be cheap, get 4 or 5 made up - the extra cost will be minimal compared to
the first one and you will have spares for the future.

It could be as simple as getting some more flexible hose - the stuff I've got at the moment is very thick-walled and doesn't like going
round corners. I really don't have the space to make a big loop with that stuff.
It looks like I'll probably make the pipe out of copper tube - I've got everything I need, apart from 3 or 4 right-angle solder fittings
and a couple of olives to solder on the ends. It'll be neat, and flow-rate isn't really critical.
