Twin SU manifold coolant t piece

[pirate]

Hi I've just fitted twin SU's to my 13/60 and realised that it doesn't have the extra downward outlet as the single carb manifold.

So I presume that I need to fit a t piece in the hose someone has said that it should have a restrictor in it?

I've ordered a 15mm equal t piece do I need to fit a restrictor in one of the outlets.

Any info appreciated.

I think you should be OK. The restrictor is definitely needed in the heater bypass but it's normally present in the tee off the return pipe to the pump (along the block below the manifold). The T-piece was integral to the inlet manifold on later Spitfire twin-carb setups, so perhaps you have an early (Mk3) manifold?

 I guess  if the heater lacks flow you could make a simple plug in the hose with a 1/4" hole to reduce  bypass flow
