Rrc Heater Hoses

Bit of a long shot, but does anyone happen to know the internal diameter of the heater hoses that go on the bulkhead connections on a hard dash petrol classic with no aircon please?

I need to re-plumb my LPG vapouriser in series with some standard hose and elbows and could do with getting everything ready to do the job in one go without pulling a hose off to measure it and loosing coolant!

its either 1/2 or 5/8 dia pipe.....measure the outside to see..

Doh, never thought of measuring the outside to work it out <feels a little stupid> thanks

If you are still wondering I have mine stripped and can measure them for you.

Hi stutab, I haven't had chance to measure mine yet so if you could check the bore diameter to confirm for me that would be great, thanks

Internal they are 9/16

Great, thanks
