Thanks Neil, most hoses say 60psi or more, so should definitely be ok. The temp bit makes me not so happy, looking at silicone hoses instead, they are ok for up to 180c so much more comfortable, plus a thicker wall.
I will need to order some (going to replace the other hose too and by pass the throttle body as it doesn't get below -5c here at the worst of times (lowest i remember was -3c) so in the meantime i'll get some standard epdm rubber hose from eurocar parts, £4.44 online reserve and collect for a 1 metre length.
Hands are nice and cut up. Guess what got in the way the whole time... air pipes
Ratchet flare set arrived today so will be getting rid of the pipes hopefully this weekend.
The hose that needs replacing is the 3/4 (19mm) one and its a short hose, that goes into a metal pipe that run along the chasis rail and then goes to a rubber hose to the rad. Had to get a round grip tool thing on the hose and swivel it as it had started rusted and needed some convinving to get it to detach. I
could reuse the metal pipe but it's pitted and rusty around the flanged end so i don't know how much life is left in it. I think that running a silicon hose, about 130cm length should be ok. Less joints plus a higher temp hose. The current hose has a sharp 100 degree turn in it and it's leaking at the outside edge so i will try and run the new hose so that the hot water doesn't hit such a short and sharp bend straight away. Can't be any good for a hose, as has been found out.
Picking up hose tomorrow, fitting on Sunday as i won't be in tomorrow. Will keep you guys updated. Thanks for the help and advise as always.
