I'm intending making a modification to my cars clutch master cylinder,
as in adding a more accessible reservoir, which will need to be linked
to the original by a pipe. Are there any flexible pipes to be wary of
using with hydraulic fluid?

yup, most designed for water i guess,

Someone on the bike group did this not long ago, used some small bore hose
he found in the garage,
next day the hose was 'sweating' brake fluid,

i remember the VW beetle has a remote resovoir for the brake master
cylinder, that had some blue cloth covered flexi hose between the 2, so you
should be able to get brake fluid rated hose from a VW dealer... or any of
the thousand of specialist VW parts places,

Use a flexible brake or clutch hose.

Try one of these readymade:

I'd be a bit wary about this sort of mod. Would it affect MOT?

I would ask why? Clutch hydraulics don't usually ever need topping up. If
it is leaking, it will only get worse.

Master cylinder + reservoir is difficult to check, located above the
pedal in the cabin and slave has a reputation of failing, so my plan is
to fit a second reservoir feeding the original one, but in a more
accessible location under the bonnet.

It is not presently an issue.

Most insurance companies require you to tell them about any
modifications or non-standard accessories. They often exclude from this
sound equipment and immobilisers. OTOH they may well want to know about
DVD players and satnavs (which affect eg the risks of theft from the
car). If you don't tell them they may not be able to deny a claim (if
the claim has nothign to do with the modification). But IIRC the
general principle of insurance is "utmost good faith" and this applies
before and after the contract - in other words you have a duty to tell
them about anything which might affect the risks they have insured.

I don't know enough about cars to say what if any effect a secondary
reserve for clutch fluid might have on risks. It did occur to me that a
load more hydraulkic fluid under the bonnet where it gets warm (at
least) and where, if it leaks, it can hit really hot metal might just
possibly be seen as an additional risk

No, he didn't. He used some hose he bought new as suitable for clutch

That is a really strange arrangement. I can't recall ever seeing a hydraulic
reservoir in any production vehicle passenger compartment.

Remote reservoirs on competition vehicles are usually connected with braided
'aeroquip' type hose with threaded end fittings and that is what I would choose
but I would expect a silicone based hose (think exhaust hose from a model shop)
to be suitable for a glycol based DOT 3 / 4 fluid. Getting a correctly sized
hose clip could be more of an issue.

oh, ****, sorry mate, my brain is past it's use by date,

i remember people thought he was using it on the pressure side, and it went
down hill from there.

do forward control vans count??
the VW LT i had, whilst it had a cable operated clutch, the brake master
cylinders resovoir was mounted inside the dash board, you lifted a flap on
the top of the dash up to get at it,

i recall the brakes were a ******* to bleed, so i had a garage use their
pressure bleeder, only the seal on their cap wasnt that good, and it ****ed
half as much brake fluid out as it did into the brake system.... of course
this ended up in the passengers footwell.

I never told them when I swapped my MKII Escort engine from a 1.3 to a
1.6:-)

It's the definition of a modification that I was interested in. When I
insure the van I am always asked if it has racking or shelving. I don't, but
apparantly it is cheaper to insure the van if it had them!!!

I am always asked when insuring the van about sign writing on the van. I
often use magnetic signs so I just say "none".
