Fuel Hose diameter for cold start system on 72 911T

Does anyone know the fuel hose diamter for the cold start system on 72 911T with mechanical injection. This is the fuel hose which comes off the top of the fuel filter and runs to both sides of the motor. . .

My car is in a garage on the other side of town and I want to order the parts. . .

Does anyone have any preference for hose clamps?

Thanks.

Ian,

The German, fabric-covered hose is 4.5 mm x 9.5 mm:

1. Valve to 1st 'T' is 400 mm long.
2. 1st 'T' to 2nd 'T' is 550 mm long
3. Short piece from 1st 'T' to #3 squirter is 35 mm.
4. Between all squirters is 110 mm long.
