Thanks Malc. I have a hard copy. I have spent more time on valve springs and other fiddly bits and had not looked at hoses, just presuming that they used the same heater connection as the Marina, don't ask me why I thought that. I am just getting to the hose replacement stage and am looking at better ways of doing things. The original hoses have done well, but are now looking a bit tired, with a few areas almost rubbed through. Twenty odd years ago there was not so much choice to confuse you.

Yes, the 1800 Land Crab hose fits. I just had to fit an alloy extender and hose onto the radiator and job done. Thanks for reminding me. The rest of the hoses have come from Hose World, although they short delivered an alloy joiner, which I am debating with them about.
