What size

[LongBaz383BHP]

What size is the ID of the advance/retard pipe that goes from the distributor to the plenum. Also the one that t goes from the gold /brass thing that goes to the back of the engine. Sorry for the non tech talk.
Thanks Barrie

The vacuum advance is normally a solid plastic pipe with rubber end connectors the I'd would be about 1mm I should think, if your changing it to rubber vacuum hose then a 1mm would fit the plenum, not sure of the dizzy end though,
The idle bypass hose is 4mm from memory
Probably all wrong as I'm not with the car

Thanks for the reply Richard. I will get myself down to the local Motor factors.

Barrie, I'm bound to have on in the garage thinking about it, maybe two!
