What is the hose size on the two coming off the fuel rails to each carb,  and also on the inlet and outlet on the mechanical fuel pump. Thank you.

I think from the fuel rail to the carburetors may be 1/4" or 6 mm. I would think the fuel line between the hard lines and fuel pumps would be 8 mm since 5/16" fits nicely. I would think 10 mm (3/8") would be too loose. That is only my opinion since I didn't look it up in the FSM.

thanks guys

By yourself a micrometer. Less than $10 at Harbor Freight. Measures inner and outer diameters both standard and metric. A must for DIY'ers.
