Does anybody know off the top of their head what size flexible oil hose is required for the above boiler?
Father in law informs me his is leaking (or at least thats where he thinks its coming from) so I'd like to pick the right one up to avoid two journeys if it is that at fault.
Could be anything. Depends on what the manufacturer used at that particular time, or whatever some service guy has used. Some put any old thing on.
Worcesters tended to use 1/4" hoses with one bent end, but sometimes the bent end was male for into pump and some were female for onto a hose nipple.
