You will have the same minor headache making it all connect up as I did.

The bottom of the expansion tank ideally wants to tee into the bottom hose. You could make a reducing T/elbow like you did for mine and use any size outlet on the tank you like. The top of the tank wants to be 8mm ID, assuming you intend to gather the various small hoses together (top of thermostat, couple from the block and the small outlet from the top of the rad) and have them terminate there. They are all 8mm ID hose.

I am by no means expert on any of this (or anything). I just followed the advice I was given at the time and it's working great. Regurgitating it here in case it helps

That's the job. I found there was another 8mm hose coming off the block which I tee'd into the top of the expansion bottle.

being lazy now, if ive got some 100mm dia tube and want a tank approx 1ltr, what would be the cutting length.
I think that 150mm long would give me about 1.2 lts of water, is this about right?.

Somebody should have paid more attention at school.

Car ran well both ways. Doesn't like "slow" though. Bit on the weak side but I'll soon sort that. I'll try and get round to see you this week.

Yep, when I drew that diagram I forgot that I'd ditched the T piece that feeds into the throttle body choke / cold start valve and also into the header tank or top of the rad on the bike (not sure which off the top of my head).

Mine is just plumbed so the 8mm bleed from the water pipe outlet goes directly into the choke, then the outlet from that goes straight into the block. It might make bleeding a little trickier in theory but Ive never had any problems, and saves having another T and another inlet into the expansion tank.
